    Abstract: A device for rotary or linear position sensing includes a stator with a plurality of teeth, an excitation winding wrapped around at least some of the plurality of teeth, and multiple sense windings for detecting changes in voltage output. The windings are in two sets in which each set can independently determine the change in voltage output. A control circuit generates a first output signal representing a relative position of the stator based on excitation of the first sense winding set by the excitation winding and a second output signal representing a relative position of the stator based on excitation of the second sense winding set by the excitation winding.

    Abstract: An electric motor comprises a rotor and a stator having a yoke. The yoke includes a plurality of teeth mounted to the yoke and being aligned substantially parallel to an axis of rotation of the motor, each tooth including a first radial end adjacent to the yoke and a second radial end extending from the yoke, a plurality of field coils, each field coil being wrapped around a tooth, and a coolant circulation path including a first coolant channel defined between adjacent field coils and a second coolant channel defined between adjacent field coils and between the first radial ends of adjacent teeth. A third coolant channel may be defined between adjacent field coils and between the second radial ends of adjacent teeth.
