Some advice on an idea of home buil electric budget car
hey,
like whenever i go and see someone building electric car,they use some DC jet engine starter electric motor.But where the heck to get one? 
On the other hand there are plenty AC engines around.Like it is not difficult to find 2,2kW 220/380 V second hand engine for like 75 E !
Recently i found a 400V 9,5 kW 50Hz for 150E! those things are cheap,i got surprised
How much would cost to build a say 120V DC (10 car batteries) to 400V AC converter capable of 25 A(or should it be 75 A due to the electric motor starting current)?
Best would be to run an electric motor on the highest possible voltage(low discharge current for batteries=> their longer life,also less resistance/heat losses).
So i thought of 'repairing' and electric motor through rewinding it for say 1200 V operational voltage.
My objective is to design a conversion under 1500E with second hand parts capable of running a car in the city conditions for min 2h.Onboard 3-5kW gasoline-electric generator,that i would tune up for economy.Pack of batteries recharged by generator on the long trips,recharged from the grid for short trips.Electric AC engine.Some controls.
any opinions?if u know anyone who knows how to build converters can u direct him here for some input?
