High speed brushless motoris composed of motor body and driver. Brushless motor is a typical electromechanical integration product. Because the high speed brushless motor is operated by automatic control, the high speed brushless motor will not add another starting winding on the rotor like the synchronous motor with heavy load under variable frequency speed regulation, and the high speed brushless motor will not produce oscillation and out-of-step when the load changes.


High speed brushless motor small and medium capacity

High speed brushless motor small and medium capacity brushless motor permanent magnet, brushless motor now mostly use high magnetic energy product of rare earth Ndfeb (ND-Fe-B) material. Therefore, the volume of rare earth permanent magnet brushless motor is one frame size smaller than that of three-phase asynchronous motor with the same capacity.


High speed brushless motor structure, high-speed brushless motor and brush motor have similarities, high-speed brushless motor also has a rotor and stator, high-speed brushless motor and brush motor structure is the opposite; The rotor of brushless motor is the coil winding, the high-speed brushless motor is connected with the power output shaft, and the stator of high-speed brushless motor is permanent magnet steel. The rotor of the high-speed brushless motor is permanent magnet steel, which is connected with the output shaft together with the shell. The stator of the high-speed brushless motor is the winding coil. The high-speed brushless motor removes the commutation brush used by the brushless motor to alternate the electromagnetic field, so it is called the high-speed brushless motor.
