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 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 switched reluctance motor. The motor includes a first member having a plurality of teeth arranged in a plurality of phase groups, each phase group including two teeth mechanically joined together through a magnetically permeable bridge. The motor also includes a second member mounted adjacent the first member allowing relative movement between the first and second members, the second member having a plurality of teeth evenly spaced from one another by a pitch in a direction of relative movement between the first and second members. Each phase group includes a first tooth and a second tooth which is separated from the first tooth by a phase group tooth spacing in the direction of relative movement between the first and second members, the phase group tooth spacing equal to a whole multiple of the pitch plus a skewing factor or a whole multiple of the pitch minus the skewing factor.
