Consequent-pole vernier permanent magnet motor

The invention belongs to the technical field of motors, and particularly relates to a consequent-pole vernier permanent magnet motor. The consequent-pole vernier permanent magnet motor comprises a stator and a rotor arranged outside the stator. An air gap is formed between the stator and the rotor; the stator comprises a stator iron core and a stator winding arranged on the stator iron core; the rotor comprises a rotor iron core and a permanent magnet arranged on the inner wall of the rotor iron core; the stator core comprises stator teeth and a stator yoke, and the stator teeth and the stator yoke form a stator slot for accommodating the stator winding; the rotor core comprises rotor teeth and a rotor yoke, and the rotor teeth and the magnetic pole units are alternately distributed in the circumferential direction to form a consequent pole structure. According to the invention, under the condition that the torque density is basically unchanged or improved, the use amount of the permanent magnets in the verni
