ABSTRACT:
A variable reluctance electric motor includes a stator having a plurality of radially inwardly extending poles which are divided into a plurality of longitudinal sections. The cross sectional shapes of the first stator pole sections are different from the cross sectional shapes of the second stator pole sections. A rotor is supported within the stator for relative rotational movement and includes a plurality of radially outwardly extending poles which are divided into a plurality of longitudinal sections. The cross sectional shapes of the first rotor pole sections are different from the cross sectional shapes of the second rotor pole sections. The first rotor poles are longitudinally aligned with the first stator poles so as to interact therewith when electrical current is supplied to windings provided on the stator poles. Similarly, the second rotor poles are longitudinally aligned with the second stator poles so as to interact therewith when electrical current is supplied to windings provided on the stator poles. The magnitude of the total torque generated by the motor as a whole is equal to the sum of the magnitudes of the individual torques generated by (1) the interaction of the first rotor poles with the first stator poles and (2) the interaction of the second rotor poles with the second stator poles.
