ABSTRACT:
A system and method of controlling motor temperature is based on computed motor power dissipation and a thermal model of the motor, rather than a measured motor temperature, in a control loop that limits the motor drive to prevent overheating. An ambient temperature sensor senses the ambient temperature near the motor, and a determination is made of the motor power dissipation. The motor winding temperature is estimated based on the sensed ambient temperature and the determined motor power dissipation. A maximum motor power dissipation that would raise the motor temperature to a predetermined maximum temperature value is determined based on the estimated temperature. The motor power dissipation is limited to a value that is below the determined maximum power dissipation.
