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.

Abstract: An electric machine includes a stator and a rotor energizable by magnetic fields produced by the stator when receiving a stator current to produce relative motion between the rotor and the stator. A controller is configured to send the stator current through the stator at a current angle measured from the closest one of a pole of the rotor, determine a desired operational output of the electric machine, and determine a desired rotor motion corresponding to the desired operational output of the electric machine. The controller is further configured to calculate a vector control modulation applied to the stator that elicits the desired rotor motion, and adjust the current angle of the stator current based on the vector control modulation to cause the rotor to perform the desired rotor motion and achieve the desired operational output of the electric machine.

Abstract: An electric machine includes a stator defining multiple stator poles with associated stator windings configured to receive a stator current. The electric machine also includes a rotor defining multiple fixed rotor poles with associated rotor windings, wherein the rotor defines a field energizable by magnetic fields produced by the stator windings when receiving the stator current to produce relative motion between the rotor and the stator and wherein the rotor is maintained in synchronicity with the magnetic fields produced by the stator during operation of the electric machine. The electric machine also includes a rectification system configured control against an alternating current being induced in the rotor poles as the field is energized by magnetic fields produced by the stator windings when receiving the stator current.

Abstract: Disclosed are systems and methods for motor control using piecewise affine modelling. An electronic controller may determine current values for a motor in a rotational reference frame. Each current value may be associated with a dimension of a set of dimensions of the rotational reference frame. The electronic controller may further determine, based on the current values, a flux linkage value for each of the set of dimensions of the rotational reference frame using a piecewise affine map. The electronic controller may further determine a target flux linkage value for each of the set of dimensions of the rotational reference frame. The electronic controller may then control a power switching network coupled between a power supply and the motor based on the flux linkage values and the target flux linkage values.

Abstract: A method of controlling an electric machine includes: energizing stator windings of a stator by a stator current, producing a stator magnetic field within the stator by the energized stator windings, modifying a corresponding rotor magnetic field within a ferromagnetic material within a rotor by the stator magnetic field, generating a force tangential to the rotor by a shift in the stator magnetic field, moving the rotor by the generated force tangential to the rotor, resisting a decay of a magnetic flux within the rotor by current within the rotor windings in response to the shift in the stator magnetic field, and achieving a target operational output of the electric machine. The stator magnetic field and the rotor maintain synchronicity with one another during operation of the electric machine.
