S.A.T. The motor consists of the main motor body and the driver, and is a typical mechatronic product. A brushless motor refers to a motor without brushes and commutators (or slip rings), also known as a commutator-less motor. As early as the nineteenth century when motors were born, the practical motors produced were of the brushless type, namely AC squirrel-cage asynchronous motors, which have been widely used. However, asynchronous motors have many insurmountable defects, resulting in slow development of motor technology. Transistors emerged in the mid-twentieth century, leading to the use of transistor commutation circuits to replace brushes
