Its main features are two: First, the high-speed rotation of the rotor; Second, the iron core stator winding currents and high frequency flux. Which determines the key technology is different from ordinary motor speed motor specific. Hereinafter referred to as the brushless DC motor (BLDC) with the development of power electronics technology and new permanent magnet materials rapidly maturing of a new motor. Its small size, light weight, high efficiency, low inertia and high precision control, while retaining the normal DC motor is widely used in excellent mechanical properties Servo-controlled areas, CNC machine tools, robots and so on. In recent years, with the continuous expansion of brushless DC motor applications of various control algorithms and control strategies have also emerged in order to facilitate the theoretical analysis and validation of various control algorithms and strategies to establish the correct model of a brushless DC motor is very important. Therefore, the high-speed permanent magnet motor prospects are very bright. However, there are many technical difficulties in high-speed permanent magnet motor design process.
