Wow! Haven't been here since a long time ago.

Just letting everyone know that the Australian electric motorcycle racing series, eFXC is starting again on the 15th of May at Mallala Raceway, about...

I got to see Jon's new motor for the Catavolt on the weekend - very impressed with it's low weight. Looking forward to seeing how it goes at Sydney next month.

Yeah, Rinehart kit is top shelf. They are good prices for what you get. Brett is a good bloke and has helped us out enormously, so it would be great if he could sell a few bikes too. Dunno about...

Skip to 33 minutes to see a 2 minute highlights reel of the racing at Winton last August.

We should get another one for...

After another successful round of electric motorcycle racing at Wakefield Park, Mike, Danny and I were drinking beers in the hotel lobby waiting for the MotoGP to come on telly. This older, rotund...

However those who live next to them and receive a cheque each month from the generator seem to be immune to these ailments...

For racing, I've found that connecting the front brake switch to the controller's inputs was pretty handy, provided the rear brake was not connected. IF you are ever going to need some brakes while...

Wow. Fabrication skills by the truckload there!

Nice work man ;)

Yep, Jon has that hub motor humming alright. It was very close to it's limit though - we could smell the varnish :O
Hopefully you can find a way of getting a few more kilowatts in there, cause...

That's a pretty serious fault with an inverter... Any idea what happened? That must have frightened the crap out of you!

Australian design rules also require any bike or scooter to have an additional, conscious step between turning the bike on and twisting the throttle. It has to be analogous to pressing a starter...

That's really cool! Did you have any idea that Tesla were going to set up there? Can any EV rock up and use their DC fast charger (assuming its all ChaDeMo or Combo capable)?

I've ridden the Sea...

What? No Voltron Evo? :P

We still can't buy Brammos in Australia. Or lightning, or ...

In my mind, AC motors (BLDC, PMAC and ACIM) all win hands down. They can all be liquid cooled because the bit that gets hot is the bit that's stationary. They have no electrically conductive parts...

Quite an impressive volumetric energy density on these cells - 260 Wh/l

Reminds me of Red Green's Christmas Dinner :lol:

Ammonia is not exactly inert stuff, from an environmental and toxicology point of view. Cool stuff all the same.

I don't know. Without field weakening it spun up to about 3700 rpm and wouldn't go any faster. With about 100 amps of ID current we are able to spin it all the way up to 4950 rpm (on the stands)...

Well what a hoot! Round one of the Australian eFX Championship has been and gone, and the O'Hanlon Electric Motorsport sponsored Voltron Evo couldn't have had a better run. Our rider, Danny Pottage...

Actually no, we hit a wall because the motor wasn't tuned properly. If field weakening in a PM motor means you add current before the synchronous point to defeat back EMF, we were trying to add it...

Well Voltron Evo is an interesting example of reaching base speed.

We originally put a 17:42 reduction on the final drive. Assuming the motor could be spun to 5000 rpm this would give a...

A few pictures of the finished bike:

Short ride-by to prove it does move :)

I want an analogue speedo and rpm meter for my race bike. km/h on the outside, rpm on the inside. EV Fuel gauge on the side, a few LEDs for various warnings and that's it. Too many bells and...

Any reason why you don't want to run the motor at it's rated voltage? It would be a slow bike at 1750 rpm - what are the current ratings on the motor? You'll hear it often around here - acids are a...

Spoonman - that's cool. How do the smarts inside the pilot pins determine whether or not you're plugging into a 10 A, 16 A or a 32 A connection?
