I have this motor sitting around and was wondering if it might work for an electric car (which i doubt as it is pretty small) or maybe for an electric motor cycle?
The only issue with that motor is its designed for high voltage. That means you'd need a high voltage pack as well as an AC motor controller. Also, the rating of 2.8 kW isn't real high. It might be enough for a motorcycle, but packing in that many batteries into a motorcycle would be a real trick.
It might be nice for an electric bicycle if you could find a way to string together a whole pile of small batteries, ones like you use for model airplanes might work well, but good luck finding a speed controller for it.
