Abstract
A method and system for limiting the operating temperature of an electric motor is provided. A maximum operational temperature of the motor is determined. A current operational temperature within the motor is sensed. A maximum allowable power dissipation of the motor is calculated based at least in part on the maximum operational temperature and the current operational temperature of the motor. A torque command for the motor is generated based on the maximum allowable power dissipation.
