Abstract
Provided is a method for preventing overheating of a traction motor in an electric vehicle. The method for preventing the overheating of the traction motor in the electric vehicle includes identifying magnitude of an output load of the motor, identifying a loading time of the motor on the basis of the identified magnitude of the output load, comparing the identified loading time to a preset critical time, and controlling output torque of the motor according to the comparison result.
