摘要： 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.

摘要： 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.

摘要： 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.

摘要： Systems and methods are provided for controlling and simulating a motor. An electronic motor controller determines present motor information and a motor control parameter set based on the present motor information and a rotating reference frame of the motor. The rotating reference frame has independent input channels that decouple an intended output response in a stator D-axis component and a rotor field (R) component of a direct-quadrature-null-rotor (DQNR) reference frame. The electronic motor controller further controls the motor based on the motor control parameter set.

摘要： An electric machine having a thermal management system includes a stator having a stator core, and a rotor having a rotor core that is moveable relative to the stator. At least one of the stator and the rotor include one or more windings. One or more coolant cans encapsulate one or more of the windings disposed on the at least one of the stator and the rotor in an interior compartment of the coolant can. The interior compartment of the coolant can defines a coolant flow passage through the one or more windings. The coolant can includes a coolant inlet and a coolant outlet in fluid connection with the interior compartment of the coolant can. The interior compartment of the one or more coolant cans are fluidically isolated from the stator core and the rotor core.
