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: Various embodiments are described herein for a system and method to eliminate mutual flux effect on rotor position estimation of switched reluctance motor (SRM) drives at rotating shaft conditions without a prior knowledge of mutual flux. Neglecting the magnetic saturation, the operation of conventional self-inductance estimation using phase current slope difference method can be classified into three modes: Mode I, II and III. At positive-current-slope and negative-current-slope sampling point of one phase, the sign of current slope of the other phase changes in Mode I and II, but does not change in Mode III. In one example embodiment, in order to operate the self-inductance estimation in Mode III, a variable-hysteresis-band current control method is proposed for the incoming phase and variable-sampling method is proposed for the outgoing phase.

Abstract: A double-rotor switched reluctance machine includes a stator, a first rotor, and a second rotor. The stator and the first rotor operate as a first electric machine and the stator and the second rotor operate as a second electric machine. Each electric machine has an output torque profile that fluctuates periodically between a maximum and a minimum instantaneous torque. The double-rotor switched reluctance machine is configured so that when the first and second electric machines are operated at a common electrical frequency, the first and second maximum instantaneous torques are temporally offset, thereby reducing the overall torque ripple of the switched reluctance machine. Additionally, or alternatively, a double-rotor switched reluctance machine is configured so that the first and second rotors are radially offset from each other to reduce a net radial force imposed on the stator by the operation of the first and second electric machines.
