Title:
A MULTI-PHASE PERMANENT MAGNET ROTOR MOTOR WITH INDEPENDENT PHASE COIL WINDINGS
Document Type and Number:
WIPO Patent Application WO/2023/029788
Kind Code:
A1
Abstract:
A multi-phase permanent magnet rotor motor comprises a plurality of phase coil windings with each phase coil winding having two free ends and the plurality of phase coil windings being without a common node. A controller is provided comprising a plurality of full-bridge inverters. Each full-bridge inverter has two output ends electrically connected to the two free ends of a corresponding phase coil winding. The controller is configured to operate the plurality of full-bridge inverters to output pulse modulated control signals to their respective phase coil windings. The outputted pulse modulated control signals can comprise a combination of sine wave signals and full-bridge space vector modulation signals.
