Brushless DC motor is widely used in automobile, tools, industrial control, automation, aerospace and so on. In general, brushless DC motor can be divided into the following three main purposes:

1. It can replace DC motor speed regulation, frequency converter+variable frequency motor speed regulation, asynchronous motor+reducer speed regulation;

(1) Brushless, low interference:Brushless motor removes the brush, and the most direct change is that there is no electric spark generated when the brush motor runs, which greatly reduces the

In structure, brushless motor and brush motor have similarities, also have rotor and stator, but are opposite to brush motor in structure; The rotor of the the brush motor is a coil winding

Brushless DC motor uses semiconductor switching devices to realize electronic commutation, that is, electronic switching devices are used to replace the traditional contact commutator and brush.

The stator winding of motor is usually made into three-phase symmetrical star connection, which is very similar to three-phase asynchronous motor. The rotor of the motor is attached with
