What is a brushless motor?

2023-12-11 17:30

Since the brushless motor is self-controlled operation, it will not add another starting winding on the rotor like a synchronous motor that starts under heavy load under variable frequency speed regulation, nor will it produce oscillation and out-of-step when the load changes abruptly. The permanent magnets of small and medium-sized brushless DC motors now use rare earth neodymium iron boron materials with high magnetic energy levels. Therefore, the volume of rare earth permanent magnet brushless motor is smaller than that of the same capacity three-phase asynchronous motor.

The stator windings of brushless motors are mostly made of three-phase symmetrical star connection, which is very similar to three-phase asynchronous motors. The rotor of the motor is glued with a magnetized permanent magnet. In order to detect the reach of the motor rotor, a position sensor is installed in the motor. The driver is composed of power electronic devices and integrated circuits, and receives the start, stop, and brake signals of the motor to control the start, stop, and brake of the motor.

The operating efficiency, low-speed torque, and speed accuracy of brushless motors are better than any control technology inverter, and they have become a driving force for the rapid development of the model field, so they deserve the attention of the industry.
