Description

technical field [0001] The invention relates to a motor control device, in particular to an axial magnetic field memory motor control device. Background technique [0002] Permanent magnet synchronous motors have many advantages such as high power density, simple structure, and high efficiency. With the continuous development and improvement of the properties of permanent magnet materials, permanent magnet motors have been widely used in automobiles, national defense, agricultural production and daily life. The axial magnetic field memory motor not only has the advantages of a permanent magnet motor, but also can broaden the speed regulation range of the motor by changing the strength of the air gap magnetic field of the motor by applying a pulse current. This kind of motor not only reduces the cost of the motor, but also its basic performance index is better than that of the permanent magnet synchronous motor, so it has a good application prospect in the electric vehicle st...
