Abstract
An electric machine is provided. A polyphase machine comprising at least one of an induction machine and an externally excited synchronous machine is provided. A power inverter is electrically connected to the polyphase machine. An inverter controller is electrically connected to the power inverter, wherein the inverter controller is configured to provide a torque command, wherein the torque command provides a torque signal to provide a plurality of pulses that pulse between a first demand torque level and a second demand torque level, wherein the second demand torque level is lower in amplitude than an amplitude of the first demand torque level and control an iprovided by the power inverter, so that when the torque signal is at the first demand torque level, rotor flux strictly increases and when the torque signal is at the second demand torque level, rotor flux strictly decreases.
