Title:
ROTOR STRUCTURE AND MOTOR
Document Type and Number:
WIPO Patent Application WO/2024/113914
Kind Code:
A1
Abstract:
Provided in the present disclosure are a rotor structure and a motor. The rotor structure comprises: a first rotor core; a second rotor core, a plurality of mounting grooves being provided in a circumferential direction of the second rotor core at intervals; first permanent magnets, which are axially magnetized and comprise a first polarity and a second polarity; and a plurality of second permanent magnets, comprising a third polarity and a fourth polarity, wherein the plurality of second permanent magnets are mounted in the plurality of mounting grooves in a one-to-one correspondence manner. The first permanent magnets are respectively arranged at two ends of the second rotor core in an axial direction, and the first rotor core is arranged on the side of the first permanent magnets away from the second rotor core in the axial direction. Projection is performed on one end surface of the second rotor core in the axial direction, and in a projection plane, the polarity sequence of the first permanent magnets and the second permanent magnets in an anticlockwise direction is the first polarity, the third polarity, the second polarity and the fourth polarity, wherein the first polarity and the third polarity are the same, and the second polarity and the fourth polarity are the same.
