Abstract: A synchronous electrical motor, which may operate poly-phase electrical power, is configured to operate at a rated flux configuration and a high flux configuration. To enable the high flux configuration, some coils wound about the stator of the electric motor can be designated bypass coils and can be selectively disconnected from the power source supplying the motor with electrical power. The remaining permanent coils continue to receive full line power and generate a rotating magnetic field with an increased magnetic flux. At startup from standstill conditions, the bypass coils are selectively disconnected so that a flux boost occurs and a corresponding increase in output torque of the electric motor.

Abstract: An electric machine includes a rotor and a stator. The stator includes a stator core having a plurality of slots. The stator further includes a plurality of drive modules configured to collectively produce an aggregate rotating magnetic field. Each respective drive module includes a power supply configured to generate a respective poly-phase alternating current (AC) output and is connected to a plurality of respective conductor windings. Each respective conductor winding includes a plurality of respective conductors, each respective conductor configured to carry a respective phase of the respective poly-phase AC output. Each respective drive module is configured to generate a rotating, poly-phase, multipole magnetic field. The rotating, poly-phase, multipole magnetic field is a superimposition of a plurality of respective mono-phase, multiple magnetic fields being generated by a respective conductor of the respective conductor winding.
