Abstract
A motor having a first portion configured to turn in a forward direction, a second portion coaxially mirrors the first portion; and a central fan between the first and second portions, and forcing air through the portions. A thermoelectric cooler element, thermally coupled to the portion is configured to cool the motor. A motor controller is electrically coupled to the first and second portions, and operates a portion in response to a condition sensed by the motor controller. The condition sensed by the motor controller is a motor torque, a motor speed, a motor casing temperature, or a zoned motor casing temperature. A method includes detecting a motor operational command; selecting a motor operational state using motor portion responsive to the motor command; sensing a heating state of a motor portion; and providing a cooling state to the motor portion responsive to the heating state.
