    Abstract: An internal permanent magnet machine (“IPM machine”) of the type used, for example, with traction motors and hybrid electric vehicles, includes a rotor having a plurality of equal-sized (e.g., rectilinear) segmented ferrite magnets arranged in one or more layers. The magnets are inserted within rotor slots that are larger than the magnets themselves, such that one or more air gaps are formed adjacent to the magnets in each layer.

    Abstract: A stator assembly for use with an electric motor includes, but is not limited to, a stator core having an inner surface and a plurality of open slots defined in the inner surface. The stator assembly also includes a winding having multiple conductors. The winding is coupled to the stator core such that a predetermined quantity of conductors is disposed within each open slot. The winding is configured to control a magnitude of a torque ripple produced by operation of the electric motor.
