Default Re: Ac electric motor

ACs do not utilize brushes, hence less heat is generated compared to your typical DC.

Their RPM max is higher than most DCs; hence the torque curve is broader. What this means is that it's advantageous for hill climbing. Plus, you don't need to use lower gears to gain top end. 12:1 gears are plenty.

ACs utilize "regenerative braking." You can get up to 30% more range over DCs.

I read on here that many people who use aftermarket, high performance DC motors have to fully depress the accelerator so that overheating/damage doesn't occur when traveling up a slope. You don't have to worry about that with AC motors. You can depress the throttle at any position.

They are widely used in electric forklifts if that tells you anything.

Since they're nowhere near as ubiquitous as DC drives, they're relatively "pricey" at this point. However, we are out to change that perception--of being pricey--because many manufacturers don't produce both the controller and motor together.
