What are the characteristics of brush DC motors and brushless DC motors? What are their functions? I believe many friends have had this question, well, in fact, it lies in four aspects, the following Vacuz to give you an analysis, I hope it will help you!

There are many differences between brushed DC motors and brushless DC motors:

As you can see from the name, brushed motors have carbon brushes, brushless motors do not have carbon brushes. Let’s take a look at the brush DC motor and brushless DC motor comparison:

1. Service life:

Brushless DC motor: can run continuously for about 20,000 hours, the normal service life of 7-10 years.

Brush DC motor: continuous operation of about 5000 hours, the normal service life of 2-3 years.

2、Using effect:

Brushless DC motor: 90-95m//s, the actual effect can be up to 5-7s.

Brush DC motor: running speed and drying time is much lower than brushless motor.

3、Energy saving:

Relatively speaking, the power consumption of brushless motor is only 1/3 of brushed.

4、Noise

Brush motor noise is much higher than brushless motor, with the continuous wear and tear of carbon brushes, the noise increases and the performance gets worse, while brushless motor is not affected.

5、Maintenance and maintenance

After the brush DC motor wears out, not only the carbon brushes need to be replaced, but also the accessories around the motor’s carbon brushes, just like replacing the rotating teeth, and importantly, the overall function will be damaged.

As brushless DC motor is a high-speed motor, the gear teeth are small, easy to carry and high power in the actual production process. Brushless DC motors do not need to replace carbon brushes during use. However, the control of brushless motors is more complicated, and there is also the relatively high price of brushless motors. Although brush DC motors must replace the carbon brushes, but it is also easier to replace the carbon brushes, motor control is relatively simple, and the motor runs smoothly.

Overall, whether it is a brush DC motor or brushless DC motor, it mainly depends on their own needs, according to their needs, to choose which motor to use, so as to meet the production needs.
