Abstract:
A motor for use with a power supply comprising:a rotor; a stator coupled to the rotor and having windings for generating a magnetic field applied to the rotor for rotating the rotor relative to the stator; a power switching circuit connected between the windings and the power supply for selectively energizing the windings to generate the magnetic field applied to the rotor to cause the rotor to rotate; a microprocessor circuit including a microprocessor controlling the power switching circuit; a housing enclosing the rotor, the stator, the power switching circuit and the microprocessor circuit; a module having a module circuit for controlling the operation of the microprocessor circuit; and a module connector within the housing and accessible through an opening in the housing, said module connector connected to the microprocessor circuit and releasably receiving the module, said module connector receiving the module and connecting the module circuit to the microprocessor circuit, said microprocessor circuit being 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.
