Title:
SHADED-POLE STARTING AND ORDINARY-POLE OPERATION TYPE ELECTRIC MOTOR
Document Type and Number:
WIPO Patent Application WO/2023/164878
Kind Code:
A1
Abstract:
A shaded-pole starting and ordinary-pole operation type electric motor, which includes a shaded-pole starting and ordinary-pole operation type induction electric motor and a shaded-pole starting and ordinary-pole operation type 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 shaded-pole starting and ordinary-pole operation method, so as to form yoke magnetic fluxes, and gathered yoke magnetic fluxes form tooth magnetic fluxes at the nearest teeth, wherein the tooth magnetic fluxes formed by means of shaded-pole starting in the shaded-pole starting and ordinary-pole operation method pass through a shaded pole to form a rotating stator magnetic field, the tooth magnetic fluxes formed by means of ordinary-pole operation in the shaded-pole starting and ordinary-pole operation method pass through an ordinary pole to form an alternating stator magnetic field, the tooth magnetic fluxes formed by using a shaded-pole starting and ordinary-pole operation splitting method pass through the ordinary pole to form a rotating stator magnetic field, and the tooth magnetic fluxes formed by using a shaded-pole starting and ordinary-pole operation mixing method simultaneously pass through the shaded pole and the ordinary pole to form a mixed stator magnetic field, thereby driving the rotor to operate at multiple rated rotation speeds.
