Title:
PERMANENT MAGNET MOTOR
Document Type and Number:
WIPO Patent Application WO/2023/245918
Kind Code:
A1
Abstract:
A permanent magnet motor (10) comprising a stator structure (100), a mover structure (200), a flux focusing structure (300), and a flux isolating structure (400). The stator structure (100) comprises a stator main body (110) and a plurality of stator teeth (120) arranged on the stator main body (110). The mover structure (200) is arranged corresponding to the stator structure (100), and comprises a mover main body (210) and a plurality of mover teeth (220) arranged on the mover main body (210), the plurality of mover teeth (220) corresponding to the plurality of stator teeth (120). The flux focusing structure (300) comprises a plurality of flux focusing units correspondingly arranged at the end portions of the plurality of mover teeth (220) or/and the end portions of the plurality of stator teeth (120). Each flux focusing unit comprises a plurality of first permanent magnets (310) arranged in the mover teeth (220) or/and the stator teeth (120), and soft magnets (320) spaced apart from the respective first permanent magnets (310), the magnetizing directions of the plurality of first permanent magnets (310) intersecting at one point. The flux isolating structure (400) comprises first flux barriers (410) arranged at the end portions of the first permanent magnets (310) in the flux focusing units. The present invention can solve the problems of relatively low output power and relatively low output energy caused by the unreasonable structural arrangement of a motor.
