摘要： An electrical induction motor may include nine terminals configured to receive nine current inputs from nine output phases of a nine phase inverter. The motor may include nine windings connected to the nine terminals, and a plurality of contactors, wherein each of the plurality of contactors may be selectively opened or closed in a circuit including the nine windings to selectively connect the windings together in one of a mesh configuration or a star configuration. Each of the windings may be selectively connected between two of the nine current inputs, with a phase angle difference between the two current inputs of 40 degrees. Each of the contactors may be selectively opened or closed to establish a span value for the mesh configuration of two, with two being the number of inverter output phases between a terminal of one of the nine windings and a terminal of another of the nine windings connected to the one of the nine windings. The motor may selectively receive a first one of the harmonics of a drive waveform generated by the nine phase inverter and a second, different one of the harmonics of the drive waveform generated by the nine phase inverter.

摘要： A hybrid electric vehicle comprises an internal combustion engine, a starter/generator (SG), a motor control module (MCM), a traction motor (TM), a clutch, and a battery. The engine provides power to SG to generate poly-phase alternating current; it also drives the wheels directly when the clutch is engaged. TM drives the vehicle wheels; it also provides braking torque to the wheels and regenerates electric energy from the kinetic energy of the vehicle. TM is a multi-speed poly-phase induction motor and is electrically connected to SG. TM, SG and the clutch together accomplish the function of “changing gear”, and no mechanical transmission is needed. MCM provides alternating current to and control SG and TM to work in their desired modes. The battery stores and provides electrical energy as needed.
