Abstract: A reluctance motor has salient teeth on both the stator and the rotor. The reluctance motor includes electrical coils that are usable to generate magnetic flux to drive rotation of the rotor. Concentrated coil windings are wound around each stator tooth. The electrical coils are arranged across all the stator teeth of the reluctance motor to enable the reluctance motor to be driven by alternating current. The electrical coils are arranged so that, when excited with alternating current, the number of magnetic half-poles is equal to the number of teeth on the rotor. The reluctance machine can operate using an inverter instead of an asymmetric bridge.

Abstract: A three-phase switched reluctance machine has a rotor, a first stator and a second stator. The rotor, first stator and second stator are coaxially and concentrically disposed. The rotor and both the first stator and second stator have corresponding poles. Only one of the stators has coils wound about its poles, while the other stator does not have any coils. A defined relationship between the number of rotor poles, the number of stator poles on the first stator and the number of stator poles on the second stator may improve the torque quality of the switched reluctance machine.

Abstract: A switched reluctance machine has a stator core salient with stator poles disposed concentrically with a rotor that is salient with rotor poles. A plurality of coil windings are wound about the stator core so that a pair of windings are adjacent each of the stator poles. The pair of coil windings induces magnetic flux in the adjacent stator poles and the rotor rotates to align the rotor poles with the stator poles having the induced magnetic flux. The rotor is rotatable at high speeds of up to 50,000 RPM and the coil windings can be directly cooled.
