Abstract: A switched reluctance machine designed for high-speed high-power operation. The switched reluctance machine has a rotor having a plurality of radially extending rotor poles, an interpolar filler positioned between the rotor poles, a stator having a plurality of stator poles extending radially inwardly from the inner surface of a machine frame, a stator winding positioned about each stator pole, wherein the stator wire has a rectangular cross-sectional profile, an axial cooling system, an end turn cooling system, and a cooling jacket positioned radially about the machine frame, and a power source configured to selectively supply electrical power to the one or more stator windings to induce rotation of the rotor.

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.

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 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.
