Abstract
One aspect provides an air conditioning system that includes a compressor housing, a motor having fan blades rotatably coupled thereto and located within the compressor housing. The motor has a rotation sensor associated with it that is configured to sense a rotation of the fan blades. This embodiment further comprises a controller coupled to the motor and is configured to increase a torque of the motor when the rotation sensor indicates that the fan blades are not rotating after an on command signal is received by the motor.
