What is a brushless motor?

What is a brushless motor? Brushless motors use square wave self-control permanent magnet synchronous motors, Hall sensors instead of carbon brush commutators, and neodymium iron boron as the rotor permanent magnet material. Compared with traditional DC motors, they have significant advantages in performance.

   

Advantages and features: Brushless motors have the advantages of low energy consumption, low noise, long lifespan, high reliability, servo control, and stepless variable frequency speed regulation;
1. A single brushless motor is not a complete power system, and the brushless motor must be controlled by a brushless controller to achieve continuous operation through electronic control;
2. Ordinary carbon brush motors rotate the winding, while brushless motors rotate the magnets in the outer and inner rotor structures. Therefore, any motor is composed of a stator and a rotor. The stator of a brushless motor is a component that generates a rotating magnetic field and can support the rotation of the rotor. It is mainly composed of silicon steel sheets, enameled wires, bearings, and brackets;
3. The rotor is attached to the neodymium magnet and rotates under the action of the rotating magnetic field of the stator, mainly composed of a shaft, magnet, and bracket. In addition, the magnetic pole pairs composed of stator and rotor can also affect the speed and torque of the motor.

The above is the basic knowledge of brushless motors, which have advantages such as high efficiency, low energy consumption, low noise, long service life, high reliability, and stepless frequency conversion control. By understanding it, we can gain some knowledge about it, which is also beneficial for later selection and use.
