Brushless DC motor and drive by the motor body composition, is a typical mechatronics product. Brushless motor without brushes and a commutator is referred to ( or slip ring ) motor, also called motor without commutator. As early as in the last century when the motor, brushless motor is practical form, i.e. AC squirrel-cage asynchronous motor, the motor has been widely used. However, asynchronous motor has many defects that can not be overcome, so that the motor technology development is slow. The middle of the century gave birth to the transistor, and the transistor switching circuit to replace the brushes and commutator brushless DC motor will emerge as the times require. This new type of brushless motor is called electronic inverting DC motor, which overcomes the defects of the first generation of brushless motor.The utility model brushless motor and electronic technology, microelectronic technology, digital technology, automatic control technology and materials science and development are closely linked. It is not limited to the AC and DC field, also relates to electric, power conversion and signal sensing fields. In the field of new motor brushless motor breed is more, but the excellent performance of the brushless motor because of price limits, its application is not very extensive. The following are the main novel brushless motor to explore and research.
