Hetai grandly launched 10 models of DC Brush Motor
Advantages of DC Brush Gear Motor
1. Simple structure
The brush motor has simple mechanism, easy production and processing, convenient maintenance and easy control; DC motor also has the performance of fast response, large starting torque, and providing rated torque from zero speed to rated speed.
2. Stable operation, good starting and braking effect
The brush motor is regulated by voltage regulation, so the starting and braking are stable, and the constant speed operation is also stable. Brushless motor is usually controlled by digital frequency conversion, which first changes AC into DC, then DC into AC, and controls the speed through frequency change. Therefore, brushless motor runs unsteadily and vibrates greatly during starting and braking, and it will be stable only when the speed is constant.
3. High control accuracy
Brush motor is usually used together with reducer and decoder to make the output power of motor larger and control precision higher. The control precision can reach 0.01 mm, which can make moving parts stop at almost any desired place. All precision machine tools are controlled by DC motor.
