Title:
SMART COILS FOR AN ELECTRIC MOTOR
Document Type and Number:
WIPO Patent Application WO/2023/150785
Kind Code:
A3
Abstract:
The disclosed electric motor includes a rotor, stator winding, cable, and motor controller. The rotor is configured to be coupled to a mechanical load. The stator winding is configured, when energized, to cause the rotor to turn. The stator winding includes an inductive coil configured to be energized with a first phase AC voltage. The stator winding includes an adaptive impedance circuit connected in parallel with the inductive coil. The circuit includes an impedance and a WBG transistor connected in series with the impedance. The WBG transistor is configured to close when an overvoltage is detected. The cable includes at least one conductor connected to the stator winding. The motor controller is configured to supply a multi-phase AC voltage to the stator winding through the cable.
