Abstract

The invention provides a disc-type motor. The disc-type motor comprises a first stator core, a second stator core and a rotor, wherein the first stator core and the second stator core are arranged axially, the rotor is arranged between the first stator core and the second stator core and comprises a disc-type support member and a plurality of magnetic steel, the plurality of magnetic steel encircles the disc-type support member and is circumferentially arranged, each magnetic steel comprises a magnetic steel body and an embedment hole, the magnetic steel body is fabricated from non-memory character magnetic steel, the embedment hole is formed in the magnetic steel body and penetrates through a width direction of the magnetic steel body, and magnetic supplement steel made of memory characteristic magnetic steel is arranged in the embedment hole. By inputting a pulse current to the magnetic supplement steel, a variable magnetic field can be generated, a constant magnetic field is generated with the magnetic steel body for synthesis, and the magnetic field performance of the disc-type motor under different rotational speed requirements is met. The invention also provides a control method of the disc-type motor.

Description

technical field [0001] The present invention relates to the technical field of disk motors, and more specifically, to a disk motor and a control method thereof. Background technique [0002] Due to its high power density, high efficiency, and simple structure, permanent magnet synchronous motors have been widely used in industry, aerospace and other fields. However, due to the limitation of the characteristics of the permanent magnet material itself, the traditional permanent magnet motor has the problems that the air gap magnetic field is difficult to adjust and it is difficult to achieve a wide speed range. [0003] Electric vehicles are driven by permanent magnet motors. When running at high speed, due to the limitation of inverter voltage, magnetic field weakening control is generally used, resulting in large copper consumption. In order to ensure the stability of motor performance in traditional permanent magnet motors, the permanent magnets must have a certain ability...
