    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.

    Abstract: An improved rotor assembly configured for magnets with differing lengths, and methods and systems for manufacturing the same. The rotor assembly may be created by selectively creating first and second tabs extending into apertures of lamination sheets. The first and second tabs may be selectively removed, depending on the different magnet lengths and the specific lamination sheet, according to one of a first finishing schedule and a second finishing schedule. The lamination sheets are stacked with any remaining first and second tabs, and other features, aligned.

    Abstract: Controlling a synchronous electric machine includes determining a rotor field current of a wound rotor of the synchronous electric machine and determining a time-rate change in field flux linkage. A rotor field voltage is determined based upon the time-rate change in the field flux linkage, and a rotor field resistance is determined based upon the rotor field voltage and the rotor field current. A rotor temperature is determined based upon the rotor field resistance. Operation of the synchronous electric machine is controlled responsive to a torque command and the rotor temperature.
