1. High Reliability of DC Brushless Reduction Motor
Because DC brushless motor is an evolutionary product of brush motor, its working principle is to replace brush commutation with electronic commutation, so there is no spark problem caused by mechanical commutation, and it can run at high speed. Because there is no need to change carbon brush regularly, the reliability of the motor will be higher, the protection performance will be better, and it is suitable for a variety of working environments.
2. Wide speed range of DC brushless speed reduction motor
DC brushless motor does not have the problem of carbon brush voltage drop at low speed and high current. It can operate normally at low speed and high current, and its speed can reach tens of thousands of rotations. Compared with brushless motor, it is easy to generate commutation sparks when running. The upper limit of high speed is low. When running at low speed and high current, the brush voltage drop is large, and it is not suitable for long-time operation.
3. High Efficiency of DC Brushless Reduction Motor
Brushless motor increases the loss of motor and reduces the efficiency of motor naturally, but brushless motor sets up the main magnetic field of motor with the magnet on the rotor, which makes it more energy-saving and efficient.
4. High Power Density of DC Brushless Reduction Motor
Brush motor has collector ring brush, which occupies the effective volume of the motor, so the power density of the motor is small, the rotor of the brushless motor has no current, the motor has low heat, the smaller volume can produce larger power, the output of the motor per unit volume is large, and the power density of the motor is large.
5. Low Noise of DC Brushless Reduction Motor
Because the brushless motor has no brush, the friction force is greatly reduced, the operation is smooth, and the noise will be reduced a lot.
The brushless DC deceleration motor has the characteristics of wide application range, long service life, up to tens of thousands of hours. The brushless motor is a digital frequency conversion control with strong controllability. It can be completed from a few minutes to tens of thousands of turns per minute.
