Abstract

The invention discloses a consequent-pole motor, which comprises a rotor and a stator sleeved outside the rotor, wherein the rotor comprises a plurality of permanent magnetic poles uniformly distributed at intervals in the peripheral direction of the rotor; the inner peripheral edge of the stator is provided with a plurality of stator teeth in the peripheral direction; the permanent magnetic poleof the rotor comprises a first permanent magnet installing groove and a second permanent magnet installing groove from outside to inside in the radical direction of the rotor; a first layer of permanent magnet is arranged in the first permanent magnet installing groove; a second layer of permanent magnet is arranged in the second permanent magnet installing groove. The permanent magnets in multilayer distribution are used; the magnetic resistance torque of the motor can be improved, so that the electromagnetic torque of the motor can be improved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to an alternating pole motor. Background technique [0002] A traditional permanent magnet motor, taking an 8-pole permanent magnet motor as an example, has 8 permanent magnets arranged around the center of the rotor along the direction of rotation, and adjacent permanent magnets have different magnetization directions. The alternating pole permanent magnet synchronous motor has only 4 permanent magnets, which are also uniformly distributed along the circumference, and the adjacent permanent magnets have the same length in the magnetization direction. The permanent magnet installation slot is called a permanent magnet pole, and the two permanent magnet installation slots The soft magnetic material between them is magnetized by the permanent magnet poles to have the opposite polarity to the permanent magnet poles, so it is called an alternating pole permanent magnet motor, and the use...
