Features of DC brushless permanent magnet motor: low operating noise, good energy efficiency; wide application range, high operating efficiency, convenient speed regulation, stable operation, stable performance, direct drive rotation technology, completely used in special places with high noise requirements.
The permanent magnet brushless motor has excellent speed regulation performance similar to that of the DC motor, and overcomes the shortcomings caused by the commutating spark caused by the mechanical commutating device of the DC motor, and has low reliability, high operating efficiency, small size and light weight. Therefore, it is widely used in aerospace, electric vehicles, medical equipment, instrumentation, servo systems, CNC machine tools, military equipment, chemicals, textiles and modern household appliances. With the continuous improvement of the cost performance of rare earth permanent magnet materials, the continuous advancement of power electronics technology and microelectronic technology, the application of permanent magnet brushless motors is becoming more and more popular.
