DC brushless motor features

2022-11-14 11:55:26 Volcano Motor Read

The brushless DC motor has the same working principle and application characteristics as the general DC motor, but its composition is different. In addition to the motor itself, the former also has an additional commutation circuit, and the motor itself and the commutation circuit are closely integrated. The motor itself of many low-power motors is integrated with the commutation circuit. From the appearance, the DC brushless motor is exactly the same as the DC motor.

The motor itself of the brushless DC motor is an electromechanical energy conversion part. In addition to the two parts of the motor armature and the permanent magnet excitation, it also has a sensor. The motor itself is the core of the DC brushless motor. It is not only related to performance indicators, noise and vibration, reliability and service life, but also involves manufacturing costs and product costs. Due to the use of permanent magnet magnetic field, the brushless DC motor can get rid of the traditional design and structure of the general DC motor, meet the requirements of various application markets, and develop towards the direction of saving copper and materials and making it easy to manufacture. The development of permanent magnet magnetic field is closely related to the application of permanent magnet materials. The application of the third generation of permanent magnet materials promotes brushless DC motors to move towards high efficiency, miniaturization and energy saving.
