Abstract
Cooling apparatus and methods for a fractional-horsepower motor. Motor cooling apparatus includes a heat shoe, a heat diffuser, and a heat pipe coupled therebetween. The heat shoe is configured to partially cover a portion of, and to receive motor thermal energy from, the motor. The heat pipe is coupled to the heat shoe, and is configured to convey the motor thermal energy from the heat shoe. Heat diffuser can be coupled to receive motor thermal energy from the heat pipe. It is configured to diffuse at least a portion of the motor thermal energy into an ambient atmosphere. A thermal sensor is coupled to the motor and configured to sense a motor thermal condition; and a fan can be coupled to the thermal sensor through a controller. The controller is configured to control the speed of the fan relative to the motor thermal condition sensed by the thermal sensor.
