Abstract
An air conditioning system includes a compressor housing and 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. The system also includes a controller coupled to the motor that 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.
