Electric Bikes - the future might be Tim Woolmers Yasa technology.

Having seen the Electric Harley Davidson on TV got me thinking about some of the latest technology in electric motors for transportation.
I am an ICE fan - I cant get excited about washing machine based engines but..................

Currently manufacturers of EV's use radial flux electric motors but a UK engineer Tim Woolmer has developed an existing design using axial flux technology. He has obtained 214 bhp & 266 lb ft of torque from an electric motor weighing just 24 Kg now developed to produce 800Nm of torque.

He is currently working on an in wheel design electric motor - imagine that on a front or rear wheel drive motorcycle. Sadly Mercedes Benz have bought out Yasa so the design might not be available to all. (YASA - Yoke and Segmented Armature).

Same here Ted, no interest in electric motion bikes from a very simple just liking it perspective. Guess the real problem is so much the energy storage though rather than ultimate motor force etc.

Some really interesting old engines around though. I looked at a Napier Lion W 12 engine in brooklands museum and tried to see how that worked.

This triple conrod being the key to cylinder arrangement.

It was Napier I believe that originally designed the Deltic diesel engine too

Quite a engineering feat  :)

I liked the two stroke diesel engine that Commer designed for their early commercials I think it was a horizontal opposed flat 6 cyl? https://en.wikipedia.org/wiki/Commer_TS3

Hazy memories as fairly young when we had Corona delivered by a little lorry that may have had that engine Ted

Remember it sounded quite cool, more motorcycle than commercial sound, but didn't know what it was then.

Vehicle was a Karrier and part of Rootes/Comma group I can see by searching now.

We had a bottle of lemonade and one other colour, that's two whole bottles for family of five to drink on Sundays, bloody luxury  ;D

Love the schematic model you posted.
