Title:
YOKE WINDING MULTI-SPEED SHADED POLE MOTOR
Document Type and Number:
WIPO Patent Application WO/2023/164880
Kind Code:
A1
Abstract:
The term "yoke winding multi-speed shaded pole motor" comprises a yoke winding multi-speed shaded pole induction motor and a yoke winding multi-speed shaded pole hysteresis motor. A yoke winding multi-speed shaded pole motor, consisting of a stator, a rotor, a support part, a motor shell, a control mechanism and other components, is characterized in that: in an armature winding of each phase, a yoke part winding is arranged in sections along a yoke part, and teeth parts are all shaded poles. Single-phase alternating current is introduced according to a multi-speed shaded pole method, so that adjacent same-direction yoke-part magnetic fluxes are mutually connected in series, and adjacent opposite-direction yoke-part magnetic fluxes are mutually gathered. The gathered yoke-part magnetic fluxes constitute a tooth-part magnetic flux at the nearest tooth part. The varying tooth-part magnetic flux passes through different shaded poles to produce a rotating stator magnetic field having various speeds, so as to drive the rotor to operate at a plurality of rated speeds.
