Electric engines revisted
I've decided what I'm going to use  and this linky should help explain what I'm doing:
http://www.vauxhall.co.uk/vaux/pages/cars/conceptCars/ampera/market.jsp
Now any ideas what motor I could use? I've been told several times to not use a gearbox because the torque will just break them so is it
possible to use one at all? I mean the Prius uses a CVT one do these exist in rwd format (does it matter? Couldn't I just weld it to the
driveshaft?)
Also I'm going to need a reverse, is there something to reverse the voltage so the motor runs backwards? This is providing I'm not using a
gearbox though.
Next is the petrol engine to recharge the batteries, I'm thinking hook it up to as many alternators as reasonably possible to generate as much
electricity as possible. I'm thinking somewhere in the region of 125-400cc bike engine should suffice?
Tbh most of the mileage I'd be doing is town driving and I'm not averse to having to wait half an hour while the engine gets some charge
in to keep me blatting. This is all experimental of course but if it works well I think I'll be touring the various manufacturer's head
offices saying "I can f***ing do it why can't you lot?"

Firstly... Hooking up loads of alternators will be inefficient... the mechanical friction from all those little bearings +brushes is BAD!
Get one big generator.....
Secondly.. In an ideal world you need an AC three phase motor with some clever electrical control circuits to modulate speed, direction and
braking.... You can use "normal" batteries or a generator and use a phase converter to give you your 3ph AC

You need to use a three phase DC motor with electronic variable speed drive, these thing do not come cheap, I have uploaded a document in my photo
archive which will help you.
Here's a link couldn't 'get it up'linky

By generator you mean those things that the road maintenance people have on their own trailer? That kind of thing? What kind of power would I be
looking at from one of those?
I shall try to look at the document now

I didn't but then I have read an article on this method being used for trucks, and now this Vauxhall. Was the Westfield one awful?

Iwas at MK a while ago, a few years now, and they had just finished an electric one for a customer, i think in finland or something.
it looked really simple (dash and where the gear stick would have been) and insted had a forwards backwards switch affair if i remember.
