Double-reverse-speed axial flux permanent magnet motor based on PCB

Abstract

The invention relates to a double-reverse-speed axial flux permanent magnet motor based on a PCB. According to the double-reverse-speed axial flux permanent magnet motor based on the PCB, two sets ofstator windings, namely the first PCB winding and the second PCB winding, are adopted, and double-reverse-speed operation of the motor can be realized without an intermediate reversing device. Moreover, the PCB windings are arranged in order and diverse in form, and for an axial magnetic flux motor with a compact structure, the problem that the conventional loose winding mode is difficult to be offline is solved, and the lightweight design of the motor is also realized. The stator iron core is of a gullet-free structure, physical decoupling between the two sets of PCBs is achieved while iron loss is reduced and torque ripple is eliminated, and double-rotation-speed output of the motor is achieved conveniently. And the integrated design of the PCB winding and the drive control is beneficialto realizing the integration of the motor and the drive control, so that the occupied space is greatly reduced. In addition, the expansibility of the mechanism is high, and the design and adjustmentof the motor are more flexible, simpler and more convenient.

Description

technical field [0001] The invention relates to the technical field of axial flux motors, in particular to a double reverse speed axial flux permanent magnet motor based on a PCB board. Background technique [0002] With the rapid development of wind power generation, attitude control actuators, ship propulsion, and electric vehicle industries, the demand for actuators with high power density, ultra-low power consumption, and miniaturization is becoming more and more urgent. As the core drive component of the above system, the performance of the motor directly affects the accuracy, response speed and stability of the entire system.
