Here is a list of Common DC Motors for use in EV conversions ranked by their continuous power.

Notes for Adding Motors:
If you are not comfortable in editing this wiki then post the information in the forums so they can be transferred to here.
These motors are ranked according to their power at their maximum voltage, statistics would vary using smaller voltages.
