1. Brushless DC micromotor has high reliability

Since the brushless DC motor is an evolutionary product of the brushed motor, its working principle is to use electronic commutation instead of the brush commutation of the brushed motor, so there is no problem of sparks due to mechanical commutation, and it can run at high speed because There is no need to replace the carbon brushes regularly, so the motor will have higher reliability, better protection performance, and is suitable for use in a variety of working environments.

2. The brushless DC micromotor has a wide speed adjustment range

Brushless DC motors do not have the problem of carbon brush voltage drop at low speeds and high currents. They can operate normally at low speeds and high currents, with a maximum speed of tens of thousands of revolutions. Compared with brushed motors, commutation sparks are more likely to occur during operation, and at high speeds The upper limit is low. When running at low speed and high current, the brush voltage drop will be large, so it is not suitable for long-term operation.

3. Brushless DC micromotor has high efficiency

Because the brush motor has brushes, the loss of the motor is increased, and the motor efficiency is naturally reduced. However, the brushless motor has permanent magnets on the rotor to establish the main magnetic field of the motor, which saves more energy and has higher efficiency.

4. Brushless DC micromotor has high power density

The brush motor has slip ring brushes, which occupy the effective volume of the motor, so the power density of the motor is small, while the brushless motor rotor has no current, the motor generates low heat, and the smaller volume can produce greater power. The motor per unit volume The output is large and the motor power density is high.

5. Brushless DC micromotor has low noise

Since the brushless motor has no brushes, the friction during operation is greatly reduced, the operation is smooth, and the noise is reduced a lot. The brushless DC micromotor also has the characteristics of wide range of use and long service life, which can reach tens of thousands of hours. The brushless motor is controlled by digital frequency conversion and has strong controllability. It can achieve anything from a few to tens of thousands of revolutions per minute.
