Application of Brushless DC motor is widely used in household appliances, automobile, aviation, medical equipment, industrial automation and other industries, with the deepening of economic development and technology, electrical equipment become more and more essential in the process of marketization. It plays an important role in people's daily life.
Brushless DC motor is a kind of synchronous motor, that is to say, the magnetic field produced by the stator of the brushless DC motor has the same frequency, and the structure of the brushless DC motor has one way, two phases and three phases. According to the brushless motor stator winding drive current is divided into trapezoidal and sinusoidal motor, general voltage motor cars, robots and other products in the 48V is even lower than 48V, while the voltage of the motor in the automation equipment, household appliances and other industrial applications is greater than or equal to 100V.
