--- The implications of doing 4 wheel motors ---

[robchalmers]

individual regulation would be necessary for straight line travel Frank, no two electric motors are even on out put and so they'd need to be balanced by the current/voltage supplied. Other wise it would be like driving with two different diameter wheels on each side, causing a constant pull to one side.

Good point. Still... I've had one-wheel-drive karts and I don't recall torque steer ever being an issue...

You could always just run several golf cart motors geared together in parallel and feed them into a diff, eliminating the complication of wheel motors, while still using the cheap power source.

I'm working on a quad AC controller to do this, and the entire purpose of the trouble is to turn that torque steering into power steering.. during braking too.

Hello -

I just noticed that the Raceabout X-Prize candidate has a motor for each wheel :

home | Electric Raceabout


Raceabout Association

What they say will set them apart: The electric Raceabout is a hand-built, two-seat sports car, with a 32-kwh lithium-titanate battery pack and four electric motors good for 268 continuous hp and 496 hp for 10 seconds. It is all-wheel-drive, with each motor driving one wheel. Recharge time is about 5.5-6 hours.
