A motor having a rotor and stator for use with a power supply. A power switching circuit connected between the windings and the power supply selectively energizes windings of the stator to generate the magnetic field applied to the rotor to cause the rotor to rotate. A microprocessor circuit including a microprocessor controls the power switching circuit. A module having a module circuit controls the operation of the microprocessor circuit. A module connector connected to the microprocessor circuit releaseably receives the module. The module connector is within a housing and receives the module and connects the module circuit to the microprocessor circuit. The microprocessor circuit is responsive to the module circuit for controlling the power switching circuit as a function of the module circuit, whereby the operation of the motor is a function of the module circuit.
