Abstract: A synchronous reluctance electric machine is described, and includes a stator including a plurality of electrical windings and a rotor disposed in a cylindrically-shaped void formed within the stator. The rotor includes a plurality of steel laminations assembled onto a shaft, wherein the shaft defines a longitudinal axis. Each of the steel laminations includes a plurality of poles and each of the poles includes a plurality of slots disposed near an outer periphery. The slots of the steel laminations are longitudinally aligned. A plurality of packets assembled from anisotropic material are disposed in the slots.

Abstract: A method for monitoring an inverter module for a multi-phase electric motor/generator includes deactivating operation of the inverter module, monitoring voltage on a high-voltage bus configured to supply electric power to the inverter module, detecting occurrence of a true fault when a change in the voltage on the high-voltage bus is greater than a predetermined threshold, and detecting occurrence of a false fault when the change in the voltage on the high-voltage bus is less than the predetermined threshold.

Abstract: An interior permanent magnet electric machine is described, and includes a stator including a plurality of electrical windings and a rotor disposed in a cylindrically-shaped void formed within the stator. The rotor includes a plurality of steel laminations assembled onto a shaft, wherein the shaft defines a longitudinal axis. Each of the steel laminations includes a plurality of poles and each of the poles includes a plurality of slots disposed near an outer periphery. The slots of the steel laminations are longitudinally aligned. A plurality of permanent magnets are disposed in a first subset of the slots, and plurality of packets assembled from anisotropic material are disposed in a second subset of the slots.
