> I'm building an electric car about the size of a small riding lawn

> My requirements are:
> 12-60 volts
> Output shaft that matches standard pulley bores, slotted or flatted
> (1/4, 3/8, 1/2, 5/8, 3/4, and the metric equivalent)
> RPMs that fall within the range of 300 - 3000, I'll make other
> adjustments with gearing.
> Decent amount of torque, couple of ft-lbs or higher, again I can make
> trade offs between RPMs and gearing
> Cost, preferably less than $100.

> I know this motors are out there and available, I just don't know how to
> find them. I look around at products other people have and know that
> they are being used in commercial products that are only a few hundred
> dollars. When look for parts for these products, the motors cost more
> the buying the product new. Unfortunately the product is outside my
> price range. I've looked at wheelchairs, RVs, electric scooters and
> bikes, golf carts, fork lifts, hand trucks, power wheels, go karts. The
> only promising source I've stumbled on is exercise equipment but the
> voltage is high and the shaft diameters seem to all be non-standard.

> Any direction to sources, contacts, products etc are greatly appreciated.
