Abstract
A variable reluctance motor is disclosed including a stator having a plurality of radially inwardly extending poles. A coil of foil wire is mounted about each of the stator poles. Flats are formed in the inner surface of the stator adjacent to the sides of each of the stator poles so that the coils of foil wire can lie flat thereagainst. A pair of rigid cylindrical retainers are provided for retaining the coils of foil wire on the poles. A rotor assembly is disposed within the stator. The rotor assembly includes a shaft having a rotor secured thereto. A plurality of radially outwardly extending poles are formed on the outer surface of the rotor. Electrical current is selectively passed through each of the coils of foil wire to cause the rotor assembly to rotate relative to the stator. Each of the coils of foil wire is wound beginning with a start winding and ending with a finish winding. The foil wires in each of the start and finish windings are employed as lead wires for connecting the coils to a control circuit for passing electrical current through the coils. A novel structure for orienting the various start and finish windings about the circumference of the stator is also disclosed.
