Hey Rip - have you seen this one?

seen it? Ive ridden it
Its Jon Eggenhuizen's VFR, Hes a motor rewinder from Newcastle
it weighes 280kg but it goes like a train. serious acceleration.
got lead acids right now but a couple of grand worth of lithium would make this perform twice as hard.

[Schtevo]

Cool, just stumbled on it on EBay and thought you might be interested, the way his motor is installed looks similar to yours from what I can see.

Looks impressive but that much weight and such small range must be limiting

Got the battery in the R1 last night and went for a ride this morning without an initial charge and
with the controller set to max output. battery voltage stood at 125v before charge
anything past 1/8 throttle and the t belt jumps so will be going back to chain drive with a similar sized
rear sprocket geared for 240kmh. still got it up to 105kmh on quarter throttle.
took 5 months to design the battery and 6 weeks to make it but it turned out well.
it came out at 48 kilo so the whole bike should be around 140kg with cables ect.
heres a shot of battery box without cells

Heres a shot of a land speed record bike currently being built by a friend of mine.
Its got 4 of the motors Im using in the R1. Its a Hyosung or some shit but its going for 200mph

http://i37.photobucket.com/albums/e62/ripperton_2008/Photo0190.jpg?t=1299472427

[triumph]

doesnt look too bad . what does it weigh .

[RIPPERTON]

over 200kg but for land speed, weight is a good thing.

So I didnt muck around blowing up my first electric motor.
After putting the chain back on I set the controller up to max amps...bad idea.
this put so much heat into the windings and rotor I think I stuffed it.
found out electric motors are very easy to pull apart, just need a basic automotive puller and a
custom flange plate. Rotor is only 7mm thick, thats a little skimpy for this app.
the Neo magnets probably also got damaged in the heat wave.

[RIPPERTON]

Turns out the windings are ok but the Neodimium magnets got overheated and lost power.
have figured out I can make a new bigger rotor with thicker magnets and inbuilt fan blades.
The second motor has gone back into the bike with some added cooling air inlet holes drilled into the
drive side casing and a modded fan (alloy disc).

Must be strange riding a bike with no engine noise

Your kidding !
this thing makes an ear piercing hum at around 40kmh and at 60kmh it goes a bit quieter just the sound smooths out and its the sweetest smoothest noise
youve ever heard on a bike. Jetsons hum FTW
Ive been playing around with the timing advance and seems the more I advance it the better it goes.
It was really wrong when I first put the motor in and wasnt pulling at all yet still getting real hot...well 80C at the cores.
Now its pulling hard with the controller set at 400 amps, still gets hot but 80 is sposed to be normal for a AC motor.
damn this thing is FUN

[Dave75]

Thanks rip

I was starting to think that it might sound like a unbalanced washing machine but I know that you would never let that happen !!!!!

[Wattie]

Won't you need a rear brake for scrutineering?

Chuck a "tank" cover on it and without a second glance, no body would ever pick it.

What happened to the belt drive??

Il cross the rear brake bridge when I get to it.
if scrutineering says put it on Il put it on... after an argument of course

Ive put the tank cover on it and weighed it 142.5kg
nothing a titanium shock spring and composite brake discs wont fix.

belt started to jump under load.
the tooth profile is pretty shallow and square unlike the harley belts, high profile and round.
back to the drawing board on that one

did 65k's on its first charge under relatively light load ie 400 amps
so it should do 30 under race conditions.
motor still needs a lot of tuning and mods.

[Jake]

This is Awesome.

[RIPPERTON]

How long does it take to charge ????

1 hour 30 min

heres the voltage monitors that basically tell me via a beep noise when the battery is flat ie when one cell block or the other gets down to 3 volts.
Also shows me how evenly the cells are charging back up.
Very important to not let any cells over volt or they pop.
http://i37.photobucket.com/albums/e62/ripperton_2008/Electric%20R1/DSC00085.jpg?t=1300173161

each of the 4 monitors does 8 cells which range from 4.2v down to 3v
http://i37.photobucket.com/albums/e62/ripperton_2008/Electric%20R1/DSC00084.jpg?t=1300173161

[Schtevo]

so it takes 1:30 to fully charge - that's from dead flat I'm assuming.

Q1. How will it go on a track day - that is if you start fiully charged, will 20 mins of race conditions be able to recharge in the 1 hour between sessions or will you get less and less charge each session?

Q2. Does it charge from a standard 240V outlet - this thing is pretty heavy duty, does that mean a 15A outlet, or even 3 phase is required to charge it?

Hats off to you Rip - I am seriously impressed with the way this is progressing, it is going to be something to see when it finally does some hot laps.

yes but dead flat is 98v
you cant take a LiPo below 2.8v or else it pops just like when you over volt it.
The monitors beep when any cell gets to 3v. theres 33 cells in series so dead flat is about 99v.
In a track day situation you would run a second battery and swap it.
The charger is 3kW 240v, spits out about 20A, dont know what its drawing but I have 28A fuses in my house.
theoretically if its putting out 136v and 20 amps it will draw 10amps at 240 volts aprox.
would definitely need a genset at Wakefield.

each cell can handle 9 amps charge so I could use a 108A charger

[r6destroyer]

RIP, Im seriously impressed with the r&d you've put into this. What is the best forum to join, website etc to find other like minded people to offer advice on making an E car. Im not interested in converting a small shitbox that already gets 7l/100 I think its pointless, but i do get that its a weight thing. I want to research converting a family sized car eg commodore wagon. Heaps of room for batteries under the wagon floor. It has to transport 2 adults and 3 kids for daily school runs etc 50 to 100k range per charge would be nice, powered of course by my 5kw grid connect solar system at home. Apologies for hijacking your thread, pm if you like. In the mean time ill check out your link to the diy forum 10 pages back.

[RIPPERTON]

Sounds like a good project r6.
people are getting good results with Headway lithium battery cells.
A friend of mine has developed battery management electronics locally.
DIY is a good forum and show up at our AEVA meetings in Castle Hill.

These blades might be too steep and could stall at higher rpm.

[RIPPERTON]

one for the AC buffs
the Kelly controller produces a trapezoidal or square wave voltage signal in the phases.
The Mars motor has Sinusoidal Neodimium magnets and is designed to work with controllers
that produce a sine wave voltage like the Sevcon.
The Mars and the Kelly isnt exactly the best marriage but it does run.
Mars has experimented with trapezoidal magnets and is Fedexing me 70 of them (5kg).
I am also doubleing the number of magnets because the magnets Ive used in the motors
so far have been demagnetized not due to overheating as I originally thought but due to overamping.
So I just have to make a new rotor thats twice as thick as the old one and move the coils apart so the rotor fits in between.
Lots of work, hope to have it running by end of next month

[RIPPERTON]

Ive made a new rotor that is effectively 16mm thick, 4x 4mm magnets.
Have moved the stators back in the casings, didnt need to widen the motor.
Motor has twice the torque now and runs much better.
Bike now gets 70km to a charge where it used to get 60km. can do 100kmh at half throttle

I didnt have to put a spanner on the bike the whole weekend, well I did have to connect the laptop and reset some parameters.
The controller is still only set at 50% which is 500 amps. Ive just gone for a short ride on 700A and went heaps faster
A 6 kVa genny wouldnt charge my battery so had to find a vacant section of pits to get some power points that wouldnt trip out all the time.

paint drying cums to mind .
wattie was on fire from the bleeches
but well dun ripper you got it to go round the fastest out of the 2 so thats a win.
but the comment over the PA "its the way of the future " mmmmmmmmmmmm

when FX 1st started in 97 they were going to keep the bikes stock or very close to and the 1 thing that was 1st changed was the exhaust rule . 1st it was complete stock then a muffler then full system.
the change to muffler was for the viewing(well listening) public and complete was coz them yamaha's and there exup .
the best part when moto gp turned up with $ strokes was the awsome noise. same as F1 and V8 taxi's

[Schtevo]

Congrats Rip - it must have been a great feeling to finally ride the bugger in anger after all the work you have put into it. Lets hope you get a few more competitors out there so you can really judge how well you've done.

What sort of times did you run, and how did they compare to your times on a "traditional" R1?

[RIPPERTON]

This was just a motor temp test run to see if the cooling fans worked or not.
The motor temp climbed up to 90C and seemed to hover there. This was with the controller set at 50%
ie 500 amps which is way more than the manufacturer intended. (180)
Also the magnets arnt what I really want in there they are just an in between magnet till I get the custom
jobs from China. I did a 1.25 in my first session then in second session did 1.29 cause the magnets deteriorated
a bit from copping 500 amps but they didnt die out alltogether which confused me a bit cause thats what the
original magnets did.
The big plus is the chassis is ok and still performs as original in spite of the major rework. I thought there would be
noticable torsion in the chassis and that would make it feel sloppy in corners.
The biggest prob I have is tire temp, they are running at 50C which is too cold. I had a slide going up the hill but caught it.
reason for this is theres not enough power, speed and generally not enough energy to keep them at 75C
This is the only missmatch in trying to make an R1 an electric race bike.
I can either change all the electrics over to a 250cc GP chassis which has smaller tires
or try to get more serious power out of the gear that I have.
This is a funny thing. You have all seen how long it has taken to get 40 kilo off both of my bikes, about 5 years.
On the weeknd I did the same in 15 seconds, just walked into Liam Wilkinsons pit and asked him if he wanted
to ride the bike, he weighes 65kg and I weigh 105, easy. but with him on it the tires run even colder.
Last thing I did on Sunday after I was happy with the cooling system was turn the controller up from
500 to 700 amps and hope there would be an extra session at the end of the day but didnt happen.
Rode it this morning and had seriously more power and still have another 300 amps to go.
2 months till Eastern Creek should see the new bigger magnets in and more top speed.

At midday today on the spur of the moment I decided to go do a track day with the R1. Rocked up and did the last 2 sessions in White group which had plenty of spodes to chew up and spit out. top speed at 700 amps was 162kmh but no idea of lap times. The bike was riding like a 125 and was a heap of fun.
winding temps were up at the 140C.

Heres a vid of the new RS35 double row drive chain I just put on the bike.
Had to make a billet 22t front sprocket from 7075 T6 and 74t rear sprocket from nylon. both sprockets will have to be remade due to prototyping errors.
The test was a quick blip to full throttle and timed rev down to stop.
I was expecting the RS35 to be quieter but if anything its the same or a bit louder but it is definitely smoother than the 520.The RS35 ratio is a bit shorter which doesnt really help, it just reduces top speed.
The 520 has almost twice the rolling resistance and a kilo heavier.
oh hay my bike just lost a kilo !!!

$1400 for 24 magnets could make 3 rotors with 8 magnets each.
I am tempted to make a rotor with 16 of these ie 32mm thick

[RIPPERTON]

I can now publish phase 1 designs as they dont work and I am moving on to phase 2 with the custom magnets
Axial air flow didnt work as it was transfering heat from the inlet coil to the outlet coil as you can see from the browny discoloration of the outlet coil.
What this does mean though is that these coils can handle 700A as long as they get fresh air ! so I am now going to phase 2 air flow with the custom magnets.
I can give a good report of Fiorenza's 4mm magnets as they seem to have not lost any of their strength even after being clouted with 1000A from my Kelly
although one of them did get a few cracks. I though the outer magnets would be weaker than the inner but they are the same. I didnt use a measuring devise to gauge the strength, just held a stack in each hand close to a sheet of steel. My custom single piece 16mm magnets are stronger even though they are 180 degree C and the 4mm's are 120C I think

I was doing 160kmh at 700A on main straight of Eastern Creek and I think I once heard the chain jump the teeth of the front sprocket as I foolishly gave full
throttle at low speed (30kmh). I have to use the throttle like a gearbox giving low throttle at low speed.
The 7075T6 rotor halves I made showed no cracks and have used a similar design in phase 2. I was able to free spin the rotor up to 5400rpm on 1000A.
Have contemplated using a different higher voltage lower amp controller 180v 800A.

Going racing at Eastern Creek on 2 July.

New magnets are in and working well with the new rotor.
It is flowing a lot of air but still needs ducting.
have done a few test rides on 1000A and has heaps of torque, maybe too much, still think it needs higher volts and lower amps.
have inquired about special pricing for Kelly controller through TTXGP reps here in Sydney.
here is phase 3 hall sensor mounting. Have flipped the hall rotor around so it faces inward and had to swap a few hall wires in the plug.

[Mr.Ed]

Are you allowed to race without a rear disk?

[RIPPERTON]

Are you allowed to race without a rear disk?

I think so
It was pointed out to the scrutineers down at Wakefield and they said it was ok.
The KERS brake can chirp the rear tire if you are hard on the front at the same time.

[Mr.Ed]

I know they wouldn't let me out with a broken rear brake lever on a track day (eastern creek)... they said I would need it in case I ran off track. Thankfully someone had a spare one.

[RIPPERTON]

Yeah thats because with no lever you have absolutely no rear brake at all. with KERS I have a rear brake even though theres no disc

Heres the chain side Ram Air manifold cncd from 17mm thick Acetal plate.
with alloy ducting and alloy duct stay. The ducts are a snug fit on the manifold without hose clamps but the stay holds them on there.

Just a question,
If you are pushing air in both sides, where is the coming out?

consider yourself lucky you're not doing rips laundry

[*Oggy*]

Just a question,
If you are pushing air in both sides, where is the coming out?

I'm guessing the wind blasting past the holes is causing a negative pressure so it's sucking the air out.

[RIPPERTON]

Just a question,
If you are pushing air in both sides, where is the coming out?

this is the standard axial air flow with an external fan, doesnt work as the coil on the left gets the heat from the coil on the right.
http://i37.photobucket.com/albums/e62/ripperton_2008/Electric%20R1/STANDARDAIRFLOW.jpg

This is the current air flow. hot air exits out of holes in the ends of the cylindrical part of the motor cases. the rotor is the fan.

Big Ass trophy for winning the historic first ever electric bike race in Australia

http://i37.photobucket.com/albums/e62/ripperton_2008/Electric%20R1/FirstPlaceeFXC.jpg

Second race on Sunday was reduced from 5 to 4 laps after I had stayed up till after midnight manually balancing each cell block with 3 RC chargers at very low amperage. Decided to resume individual charging the next day at the track with a friends lab power supply. Was able to pump 17 amps into each block. The pack looks a lot better now at low voltage even though after 5 laps was still at 120v from 134v full.
The competition virtually eliminated itself, I smelt burnt motor coming around T9 hairpin and found Chris Jones parked on the onside of T1 with yet another blown Agni being picked up by tenders. Catavolt fault coded one of its 2 Kelly controllers and was basically running on 1 controller with an unfamiliar rider on board, rider no1 broke collar bone in a previous race on his super motard.

I did a new personal best lap of 2.07 on the last lap by actually using full throttle on some exits. Was surprising how much power I wasnt using the whole weekend, the R1 really launches out of turns but that pushed the stator temps up to 150C.
time for water injection

There is a story on Formula Extreme about the electric race but only gives Ripperton a brief mention as winner as the whole story bangs on about the bike that came 3rd in race one & 2nd in race two.

Why not more of a story about the winning bike?

[veitch-y]

I loved this quote from the FX story "Starting from last place on the grid, Chris hole-shot to the front, a testament to the powerful twin-motor arrangement." Made it sound like he made up alot of ground but last place was still on front row .

there was a whole other article about Ripper though .

What's the difference between the 2 classes??

But odd having 2 classes for 3 bikes...

[RIPPERTON]

What's the difference between the 2 classes??

But odd having 2 classes for 3 bikes...

Battery size
TTX75 has 7.5kWh limit on battery size
my class TTXGP (EU) or eFXC (AUS) is the unlimited battery size class. Ive only got 7kWh but Im working on a quick swap system
so in an IOM situation I would use 14kWh over the lap
some of the IOM bikes have 14kWh on board and weigh 240kg (lol)
the 2 catagory system has to go as Ive made a recommendation to TTXGP
that for safety reasons individual pack size has to be kept to a minimum (7 or 8 kWh) so
as to minimize the quantity of lithium in any one area and that all packs be quick release.

Just got water cooling system finished so went for a trackday
down the Creek. no photos but great on bike video

http://www.youtube.com/watch?v=uzHUcvzHJVU
did all 6 sessions but only 4 laps per session (16km)
except one session did 5 laps (20km) and last session did 6 and half laps 26km and bottomed the pack but didnt damage any cells.
was able to recharge with just enough time between sessions.
water cooling went well but needs 2 fans on the under seat radiator to move the air properly as I cant put it up in front of the battery.
had a few leaks but turned out to be very effective at removing heat from the stators.
bike still weighes 135kg and as you can see
absolutely chops up anything in turns.

heres one of the grand total of 4 laps I did at Winton.
$960 entry fee, thats $240 a lap but Ive asked for the entry fee to be transfered to the next race.
This eFXC thing is so expensive, for that money I could get 8 hours of track time on ride days.

Why is it double a noisy bike?????

Were kinda sanctioned under TTXGP in the UK and had to fly one of them down here for the first race to get our scrutineers trained up.
But theres the possibility of them paying freight to OS races like IOM and series winners get to go OS
good thing Im the only one in my class down here !

[RIPPERTON]

F I R E !!!
Wakefield.
After 8 laps of racing my windings caught fire and siezed the motor right as I crossed the finish line. Dragged the bike to a halt at the end of the pit wall and I looked down and saw flames licking around the casing behind the front sprocket, went out by itself pretty quick .
Got first place about 200m in front of Catavolt and Voltron.
Heres a Flyby with Jason (Catavolt rider)

http://www.youtube.com/watch?v=r5mbT_HDqiU

The problems started on Friday practice, the bike was perfect with brand new stators in. I missed the start of the first practice session because of faulty PA system so only got an out lap and an in lap but the bike was doing 155kmh on 132v 800A and really pulling hard and clean and handling lots of full throttle.
Then just before second session I got a migrain (blurred vision) so I offered the session to Jason, But as I gave him the bike I forgot to switch the water pump on and I only rmbrd when he was on the 5 lap so that basically toasted the brand new stators but they were still functioning and hadnt shorted to the cores but they were on their way out.
I did a 1.22, Jason did a 1.19.
So come race time the next day I had to nurse the bike to the finish line.
I chased Jason around the track for the first 5 laps then Catavolt had a controller shut down and reboot so he stalled coming out of a corner, I said see ya later and went solo to the line.
I won the race but Catavolt won the Championship because of my DNF at Winton. He completed more races.
Chris' Voltron had even more dramas. He crashed in Fridays practice and landed on his right Agni and crushed its brush holder to bits. Went back to Canberra and got new parts and got it going again.....that is untill Saturdays Qualifying in the wet (damp), he came past me going down the straight and I said to my self hes going to crash and sure enough up the back of the track on a right hander right in front of me it went down again on the right Agni. Chris had to remove the brush holder and run the race on one motor....which did guess what, yep smoked itself, threw its solder.
All in all the whole weekend was a big party and a lot of fun racing and blowing shit up !!!

nice work dan its coming along nicely

[RIPPERTON]

just got back from my road trip and couldnt get any track time until this afternoon.
Friday at Wakefield was rained out (bikes not water proofed yet)
met some bucket racers and they said I should ask if I could get into the bucket class the next day but wasnt to be even though I invoked the law of Burt Munroe I would be too fast for the buckets ??!!.
So drove home and caught the last session at Eastern Creek.
Unfortunately no video or photos.
New Top Speed 175.8 kph
all temperatures are under control
pack 43C
Controller 42C
Coils 98C. Didnt get radiator temp but they would be colder than 98C.
Now the right coil runs 3C hotter than the left meaning the advance or synchronisation is solely responsible for the running temp.
The pack bothers me the most because of the high IR's of the cells and the top half of the pack doesnt get the direct air blast that the bottom half gets because it is behind the frame. Also when I brought the bike home the pack was still warm so I pulled it out and propped a fan up against it to get the heat out.
I did 26km in the session but cell 17 crashed and caused me to stop.
theres easily 32km of racing range in that pack.
Anyway the bike is as agile and fast in corners as ever and I can really feel the 141kg although the smallish motor was tripping the controller out any time I went over 80% current (340A).

Incredible piece of engineering RIP.

[RIPPERTON]

Thanks Blackzook.
Did Dyno run today at Campelltown Motorcycles
dont focus on the number too much (61hp) Im not sure if its too accurate.
we did 2 runs the first one was 53hp and the second was 61hp, Shannon said he rolled the throttle on differently the second time.
The Dyno speedo read 200kmh but I only get 175 on track so I will
be making a smaller front sprocket so I can use up all the revs.
what is interesting is the shape of the torque curve and its position in relation to the hp curve.

Dan, that label of 70nm thats drawn in, its on the graph at about 52nm?

How's it feel to accelerate though, with it being light is it nice n punchy? The top speed would suck when doing the north circuit !!!

[Mr.Ed]

Probably fun to race against the 400's if it's light enough

[Tom]

Foot pounds not Nm

[triumph]

61 HP is not bad for a electric razor .

[RIPPERTON]

52 ftlbs is 70Nm
Punchy is the word
Torque is the real thing bitches
top speed 175kmh no lift for T1.
Ed go tell Aus Superbike admin Id like to race the Tards and 400's, I already have.
They want us in our own category for exposure cause there are private intrests sponsoring the Ebikes.
I tried to get in the buckets too at Wakey on Saturday but said no too different and would woop em.

when is the next outing at eastern creek.

[RIPPERTON]

first round of Australian 2012 TTXGP eFXC Wakefield
WOW what a weekend. Only Ripperton and Catavolt showed up.
some very close racing, almost too close sometimes.
in Friday practice we got a good idea of the pace between the 2 bikes.
There was almost nothing in it. The combined bike rider weight was
Ripperton 141+105=246kg 61hp
Catavolt 175+75= 245kg 60hp
I had advantage on corner entry due to better brakes
Catavolt had advantage on exit due to more copper (torque) and 2 controllers
I had to use the Kellys boost function to avoid overamp cutouts.
The controller ramped down amps when it gets feedback from motor.
Made the bike very slow out of corners.
even our top speed were similar, I clocked a 170.8kph in a draft behind Catavolt but would get a 169kph in the wind.
Catavolt top speed was about 165kph.
On Friday we kept ramping up our own settings to squeeze a bit more out.
My pack was behaving so well with the new BMS I set draw on battery to 90% and the pack would come off track at max 48C and cool down straight away even while charging at 24A.

Racing was damn close.
Saturdays race was reduced from 6 to 4 laps due to delays in the days schedule caused by a few serious gas bike wrecks and the Ambulance had to go to Hospital twice.
Catavolt got the start but was taken in l2 when I outbraked him in t4.
got me back in t10 a lap later. I got him back again in t2.
Then in l4 got me on brakes in t10 but unwittingly pulled out his lanyard 50m before the finish line. I was gifted the win but got fastest lap which now stands as race lap record for eFXC catagory. 1m15.607.
Race 2 Sunday also cut down to 4 laps, Jason learnt all the possible places I could overtake under brakes and studiously slammed the door shut every corner of every lap so had a lot of trouble overtaking him. We nearly crashed at least 6 times on Sunday where I had to back out each time to avoid a crash. came in second 1.2s behind. also fastest lap in race 1.15.663

The combined bike rider weight was
Ripperton 141+105=246kg 61hp
Catavolt 175+75= 245kg 60hp

Mate great work as always, but your bike is 34kg lighter than his and combined weight 1kg heavier, time to call Jenny to get more competitive ;)

You must have felt like Steve Bradbury when he pulled the lanyard with the line in sight

Excellent work Rip. Thanks for the update too!

"Steve Bradbury" :pisslaugh: ;)

Jenny Craig cant ride too fast mate but Shaun Geronimi can and he weighes 60kg. He had a go on Saturday morning and loved it.
took him 3 turns to figure out the tires were crap and needed standard brake pads.
He gave me one of his used tard Pirelis.
Sooner or later I hand over the riding duties to someone else cause I aint ever getting any lighter or faster

Interesting stuff Rip, keep the updates and progress coming.
Whats next for the bike, how to improve it some more to try and gain an edge over the opposition; new tyres on the cards?
What is a rough estimate in the costs of the electrical gear in its current incarnation?

Ive got some new beefier stators coming from China direct from the manufacturer on a semi sponsorship deal. Cheap parts for stickers on the bike.
They have the same turns but wider slots and 30% more copper. $50 each 10kg. I couldnt get them rewound here in Oz for less than a grand each.
Also getting new A grade LiPo cells from China (where else) to rebuild my pack which is made from b grade cells. $6000 shipped.
I got a twin rotor motor designed and hope to get that running by end of year.
