Brushless DC motor (short named BLDCM), due to the use of electronic commutation to replace the traditional mechanical brush and mechanical commutation device, so the structure is simple, no  mechanical friction loss and reliable operation, and also offers high-speed precision, high  efficiencythe advantages of high starting torque, so it is widely used. Along with the rapid development of the permanent magnetic materials, high coercivity, remanence and energy product  advantages, can greatly reduce the body size and weight of the brushless DC motor, permanent magnet  materials and brushless DC motors the combination of the birth of permanent magnet brushless DC motor.
