Abstract: An internal permanent magnet synchronous electric machine has a rotor having a body of ferromagnetic material with a plurality of permanent magnets disposed wholly within the body and arranged in the body of the rotor as alternate North and South poles, each North and South pole formed by a pair of the permanent magnets arranged in a V with each magnet being a leg of the V with an apex of the V radially inwardly of ends of legs of the V so that each V opens outwardly in the body of the rotor at an obtuse electrical angle between the legs of the V of 135 degrees ± one degree. The rotor has an outside diameter (Rotor OD) defined in terms of an outside diameter of a stator of the electric machine (Stator OD) as Rotor OD = Stator OD / (1.7 ± 0.5%). Each North and South pole of the rotor has a pole-pitch to pole-arc ratio optimized for minimum cogging torque, maximum torque and optimized core loss.

Abstract: An electrified powertrain includes an electric motor having four or more coils corresponding to four or more AC phases and configured to generate drive torque to propel an electrified vehicle. The electrified powertrain also includes a low voltage electrical system comprising independent battery modules each configured to output a separate low DC voltage, and a power inverter module (PIM) configured to receive each of the separate low DC voltages from the battery modules, generate a separate low AC voltage for each AC phase using all of or fewer than all of the separate low DC voltages, and output the separate low AC voltages to the coils of the electric motor to drive the electric motor to generate the drive torque to propel the electrified vehicle, wherein none of the separate low DC voltages are electrically isolated and none of the separate AC voltages are considered high voltage.
