As the most critical electrical energy conversion equipment for electromechanical engineering, motors have been used in all sectors of society and economy around the world, whether it is white goods and other electrical products used in daily life, or consumer electronics such as unmanned aerial vehicles , And its various intelligent robots and other industrial control system commodities have extremely common applications. Nearly 60% of the electromagnetic energy supplied in China is consumed by the operation of the motor, so reducing the energy consumption of the motor can reasonably increase the utilization rate of electric energy. At this stage, the motor has also changed from the initial AC induction motor to the application of DC brushless motor to improve energy efficiency, reduce energy consumption, high efficiency, environmental protection and energy saving is the development trend of the entire motor manufacturing industry.
