E-Formula Extreme - Sydney presentation

Hey John,

Have you heard anything about bookings for the upcomming first race at Eastern Creek? I just reset my flights to Sydney, and will restart the crating and transporting process all over again, but I haven't seen the entry forms up on the efxc.com.au website.

Cheers,
CHRIS

Voltron, the Electric RG!

Yes, I agree on all points. The solid shaft is the only option I have for this bike, as it is too late to change anything substantially now. Centre bearings would be the only way to improve this setup, but the motor shafts are simply too short and the single load-bearing bush is no good for high loa...

You just described in intricate detail the beginnings of a wheelie http://forums.aeva.asn.au/smileys/smiley4.gif Yep, the other guys are doing exactly what I have proposed, except they have a far more solid setup than my failed effort here. This is what the shaft looks like: http://i285.photobucket....

Voltron, the Electric RG!

Hmm, seems overly complex. Every other TTX-GP entrant who uses dual Agni motors has fixed them with no flexible elements in the drive shaft whatsoever. My problem with any amount of flex in the system is that it simply creates a weak point. For the record, my shaft didn't break - it just popped out ...

That still presents me with two weak points. Even if I used a universal joint, I need to fix it to the motor on the right, and have a drive sprocket on the left. I still think a solid shaft joining them would be stronger. Something like this? http://i285.photobucket.com/albums/ll53/jonescg/Newmotors...

Voltron, the Electric RG!

Either a flexible coupling that can withstand the loads I'm putting on it (unrealistic expectation I believe) or a solid shaft with solid, long keyway couplings that doesn't flex at all (effectively one long shaft between the two motors). I honestly can't see a lovejoy coupling being able to withsta...

E-Formula Extreme - Sydney presentation

I think my bike goes like a shower of sh*t, but not when it's on the other side of the country. Oh well, it gives me time to test and improve things in the back yard and on a circuit I know, rather than in the pit garage of a circuit I don't know. In any case, I'll be there for the first race in Jul...

TNT = FAIL OK, so in the interest of electric motorsports, I would encourage all EV enthusiasts to not use TNT. They didn't pick my bike up in the two days before the Easter long weekend, meaning it wouldn't get to Wakefield Park on time by road freight. The only option was to fly it there, and TNT ...

Tell me about it. Just trying to get my bike crated over there for the shakedown is enough trouble. TNT never picked up my bike! So it's going to have to go by air cause there's no way it will make it in time Image

I ended up crating it with TNT, but not without much acrimony. They only service business, not private customers. So I got UWA to do it for me :) Should be a great weekend! I'm the rider for my own team, but if there are lighter, faster riders they are welcome to have a crack. It gets shipped off to...

The BMS is in a panel because the A123 prismatic packs don't lend themselves to having BMS modules added to them. I need to have them remotely located, and two panels of 16 either side of the bike are perfect for the task. It turns out the high voltage capacitance effect I get on my bike (that is, I...

OK sorry about the hiatus, but things have been busy at work and in the shed. I spent a lot of time stripping the bike down and replacing the sprocket with a taller gear.

I can measure a decent (reliable) current on the battery positive before the contactor, but after the contactor I'm getting crazy currents because that's where armature positive heads over to the motors...

J2 lead 2 is -ve 24 V into the controller. The 24 V out is referring to the 12/24 V converter. I have thought long and hard about it, but the risk of doing something silly like attempting to ride off in precharge mode, or something like it is too high. The controller effectively opens the relay, whi...

Here is the new and improved ignition diagram. It leaves the precharge resistor in place, since it probably only draws a significant load as the capacitors charge up, but not a lot thereafter. It also allows for monitoring of the current in with the CA (which is turned on by a switch on the dashboar...

M- cables are identical. M+ cables vary by about 30 cm. Hope this doesn't make a huge difference. I guess I won't know till I can put a current clamp on each side.
