ABSTRACT:
A self-cascaded reluctance motor is provided with an axially laminated rotor. The motor includes a stator winding having two sets of terminals and wound such that the number of poles between one set of terminals differs from the number of poles between the other set of terminals by more than two. The rotor includes a plurality of axially disposed conductive sheets and magnetic material laminations which are interleaved within each rotor segment to form groups of magnetic material laminations which lie between two of the conductive sheets. The number of conductive laminations is equal to one half of the total number of stator winding poles or an integral submultiple thereof, while the number of groups of magnetic material laminations is equal to one half of the total number of stator pole pairs or an integral submultiple thereof. Short-circuited coils can be substituted for the conductive sheets to provide better coupling between the two stator component windings and thus more output power.
