use of the advantage of the brushless dc motor: (1) motor with high efficiency, especially in the case of load range, remained high efficiency motor, brushless dc motor for the precious battery power is very important. (2) the wide speed range, the motor can run tall in the low speed range. (3) overload capacity is strong, can meet the needs of equipment projections blocked. (4) no mechanical commutator, adopts fully enclosed structure, prevent dust from entering the motor internal, high reliability. (5) motor control system easier than asynchronous motor. 6. Low noise, meet the requirements of environmental protection index of Europe and America. Brushless dc motor used in electric light source products equipment, electronic equipment, sewage treatment equipment, lithium battery equipment, logistics equipment, medical equipment, pharmaceutical machinery, hardware machinery, blood dialysis machine, coating machines, textile machines, filling machines, automatic feeder, livestock machinery, farming machinery, CNC machine tools, industrial robots, packing machines, carton machine, engraving machine, injection molding machine, air compressor, and general machinery automation control and new energy electric cars.
