Abstract
A reconfigurable electric motor (or machine) that may be reconfigured to improve performance given particular motor conditions. The motor is part of a motor system including a stator, a rotor, a microinverter network including a plurality of microinverters, and a motor controller including processing circuitry. The motor controller controls the plurality of microinverters to drive the motor in accordance with a first configuration of a plurality of motor configurations. The motor controller determines, based on determined motor conditions, to reconfigure the motor from the first configuration to a second configuration, where the first configuration has a first pole count that is different than a second pole count of the second configuration. The motor controller further controls the plurality of microinverters to drive the motor in accordance with the second configuration.
