Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I'm designing a propulsion system for an electric car as a part of a college project. I'm trying to find the minimum torque needed so the car can begin to move, i'm assuming this will be the greatest torque required for motor selection, provided the vehicle will accelerate relatively constantly and then maintain a constant velocity.

There will be direct transmission so the only loading I can think of in the car is the static bearing loading that must be overcome. Assuming I know the acceleration of the vehicle, How would I find this torque?

Thanks for any help..
