That's my biggest concern. I know that a 5 HP motor is only rated for 5 HP, but I can't see it really producing more than that without a controller feeding it more. Just being hooked up on it's own, with a contactor or a series of contactors, I just can't imagine it really being all that bad... if it were to get bad enough, I'd just hook a torque damper between the motor and transmission, I guess. I'm not really interested in building a complete EV, I just wanted to maybe build something to get around town and such.

You can compare the two options I was looking at here:
Regal-Beloit Electric Air Compressor Motor, 5 HP 15 amp - 3241192 | Tractor Supply Company
and here: Regal-Beloit Electric Air Compressor Motor, 5 HP 21 amp - 3241281 | Tractor Supply Company
They're both rated for "Comp" duty, which is continuous. I do believe they both have overheat protection, as well.
