Comparison of advantages and disadvantages of DC brushless motor and DC brushless motor

Time:2024-04-15 Views:163
    Dc brush motor: fast start, timely braking, smooth speed regulation, simple control, simple structure, cheap price. The point is cheap! The price is cheap! The price is cheap! Moreover, it has large starting current, large torque (rotational force) at low speed, and can carry a very heavy load.
    However, due to the friction between the carbon brush and the commutator, the DC brush motor is easy to produce sparks, heat, noise, electromagnetic interference to the external environment, and low efficiency and short life. Because the carbon brush is a loss product, it is easy to fail, and it needs to be replaced for a period of time.
    Dc brushless motor: Because the DC brushless motor eliminates the carbon brush, it has low noise, no maintenance, low failure rate, long service life, and the running time and voltage are relatively stable, and the interference of radio equipment is small. But it‘s expensive! It‘s expensive! It‘s expensive!
