Permanent magnet motor rotor, permanent magnet motor and processing method of permanent magnet motor rotor

The invention discloses a permanent magnet motor rotor, a permanent magnet motor and a processing method of the permanent magnet motor rotor, which relate to the technical field of motors. The permanent magnet motor rotor comprises a rotating shaft, a silicon steel sheet group and a plurality of magnetic shoes. The silicon steel sheet group sleeves the rotating shaft, the plurality of magnetic shoes are fixed outside the silicon steel sheet group at intervals along the circumferential direction of the silicon steel sheet group, two ends of each magnetic shoe in the circumferential direction are respectively and reversely arranged in an inclined manner relative to the axis of the magnetic shoe to form two diagonal planes, and the opposite diagonal planes of two adjacent magnetic shoes are arranged in parallel. Energy loss can be effectively reduced during operation of the permanent magnet motor, the overall production efficiency of the permanent magnet motor can be improved, and the production cost is reduced.
