This is because electrical energy is extremely convenient in aspects such as production, transmission, distribution, use, control, and energy conversion. A motor is an energy conversion machine related to electrical energy, and it is an important device commonly used in industry, agriculture, transportation, national defense projects, medical equipment, and daily life. As a type of motor, the brushless motor is widely used due to its advantages such as high efficiency, durability, and low noise.
