YOKE-WINDING-BASED MULTI-SPEED SINGLE-PHASE ALTERNATING-CURRENT ELECTRIC MOTOR

WIPO Patent Application WO/2023/164866

A1

A yoke-winding-based multi-speed single-phase alternating-current electric motor, which includes a yoke-winding-based multi-speed single-phase alternating-current induction electric motor, a yoke-winding-based multi-speed single-phase alternating-current synchronous reluctance electric motor and a yoke-winding-based multi-speed single-phase alternating-current hysteresis electric motor. The present invention is composed of a stator, a rotor, a support component, a shell, a control mechanism and other parts, and is characterized in that armature windings of each phase are yoke windings which are arranged along a yoke in segments. A single-phase alternating current is introduced by using a multi-speed single-phase method; adjacent yoke magnetic fluxes in the same direction are connected to each other in series, and adjacent yoke magnetic fluxes in different directions gather together; and the gathered yoke magnetic fluxes form magnetic poles at the nearest teeth, and changing magnetic poles form a rotating stator magnetic field or alternating stator magnetic field having multiple speeds, thereby driving the rotor to operate at multiple rated rotation speeds.
