Abstract: An electric device and a stator assembly for the electric device includes a stator core defining a plurality of slots spaced from each other. The stator assembly includes a plurality of bar conductors disposed in each of the slots and arranged to present a first winding path, a second winding path and a third winding path. A first set of the bar conductors of the first, second and third winding paths are configured to receive current in a parallel circuit arrangement. The stator assembly also includes a plurality of electrical jumpers electrically connected to a predetermined number of the bar conductors such that an amount of current flowing through the first winding path and the third winding path is substantially the same and an amount of current flowing through the second winding path is different from the amount of current flowing through the first and third winding paths.

Abstract: An electric machine includes a stator core defining a number of stator slots (Z). A rotor assembly is positioned at least partially within the stator core. The rotor assembly includes at least one permanent magnet and defines a number of poles (M). A plurality of stator windings are positioned in the number of stator slots and define a number of phases (M). The machine defines a non-integer slots per pole per phase value (X), which is expressed as a mixed fraction in the form of A.(B/C), where A, B and C are integers. Optimal configurations for the electric machine are specified that maximize torque while minimizing torque ripple, noise and manufacturing complexity. In one embodiment, the slots per pole per phase value (X) is 2½. In another embodiment, the slots per pole per phase value (X) is 3½.
