Electric wedge

[Act Daft]

This is different, 280 electric wedge anyone?

Thats just awesome, Just like back to the future...I love the style of the US Wedges, They just look so much more aggressive ...Over 500ftlb torque...Jeeze..I was wondering where the AFR reading was...
Imagine getting passed by it at 160mph with just a whoosh from the Electro-vibarometer...Whoops nearly gave it away...Lets just say i have technology that will boost that car like a burst of NOS...Except it don't run out...

There is a downside.

Electric means no pops, no bangs.

Im sure some strategic arching could compensate for that...It would certainly stop people tailgating you...

[adam quantrill]

With that torque curve you rip the tyres to shreds at 0-20 mph and it runs out of puff at 100 mph...

See the 16" post for why...

Can't he run the motors differently so the torque is more constant-like? I seem to remember field coils in series instead of parallel... it's been a long time...

I was thinking about this anyway for a hybrid wedge but I couldn't work out a way to keep the weight down to gain any acceleration benefit.

Electric cars? I wouldn't want to be seen dead in one. I'd rather give up driving.

Tony. TCB.

I dunno, I have had a lot of fun in them over the years, years 3-7 at the fairground, then 12-17 on the bumpers.....

[V8 Fettler]

Within reason, you can use modern electric motor drives to achieve max torque over a wide rpm range, but where's the fun in that? And it is the noise that is the highlight of the Wedge experience, from the factory, no meddling required.

Fine engineering achievement by the owner though

Rear spoiler looks crap and what's a wedge without the noise??

[superwedge]

this is the spoiler for it, that ones for push bike

The science geek here again -
As I remember, high torque comes from series connected 'leccy motors, and constant speed low (relatively) torque from parallel connected. I believe older electric trains were swopped over by driver, so they could get high torque to start off with, and then swap over for better high speed running. Don't know if this is still done.

I don't see why this wouldn't work for any electric car....

[adam quantrill]

I agree - switchover from one to the other - but I think it might be the other way around... of course all this is moot if the field is permanent magnets.

[RCK974X]

Yeah ... of course the world has changed, with the technology around permanent magnets being totally different, for example. The neodymium (?spelling?) magnets are hugely powerful. So new solutions and designs will be viable.
