Title:
ROTOR DISC, AXIAL MAGNETIC FIELD MOTOR ROTOR, AND MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/138051
Kind Code:
A1
Abstract:
The present invention provides a rotor disc, an axial magnetic field motor rotor, and a manufacturing method. The rotor disc comprises a rotor support and a plurality of magnetic pole plates; the plurality of magnetic pole plates are arranged on the rotor support in a circumferential direction; the two axial sides of each magnetic pole plate are exposed by the rotor support; the magnetic pole plate is formed by mixing magnetic steel and high magnetizers according to a preset proportion; and the thickness of the magnetic steel of each magnetic pole plate is gradually reduced from the middle of the magnetic pole plate to the two sides of the magnetic pole plate in the circumferential direction. Therefore, the sine degree of a magnetic field is improved, the generation of harmonic waves is reduced, the operation performance of a motor is improved, the use amount of permanent magnets is reduced, and a magnetic pole optimization effect is achieved.
