Is it better to have a brushless motor or a brushed motor? What’s the difference? Listen to what the motor manufacturers say

As you can see from the name, there is a difference between a brushed motor and a brushless motor. Brushed motors come with carbon brushes, while brushless motors do not. So is the motor better with brushes or brushless? Norwon takes a look at the difference between the two!

1.Service life.

Brushless motor: can work continuously for about 20,000 hours, and the normal service life is 7-10 years.
Brush motor: can work continuously for about 5,000 hours, with a normal service life of 2-3 years.

2. Use effect.

Brushless motor: running at a high speed of 90-95m/s, the actual effect can reach 5-7s of hand drying time.
Brush motor: its running speed and hand drying time is very slow, and brushless motor is incomparable.

3. Energy saving.

Relatively speaking, the power consumption of brushless motor is only 1/3 of that with carbon brush, energy saving effect is obvious, which is one of the main reasons why many manufacturers choose brushless motor.

4.Noise and service life

Brush motor noise is relatively large, much higher than brushless motor, along with the wear and tear of carbon brushes, brush motor noise will become louder and louder, while brushless motor will not be affected.

5.Maintenance

After the brush motor wears out, not only the carbon brush has to be replaced, but also the accessories around the motor, which is not only troublesome, but also increases the production cost, and the overall function will be affected.

In the actual production process, although the brushless motor effect is good, but the process of controlling the brushless motor requires higher precision, and the price of the controller is higher; while the brush DC motor needs to replace the carbon brush, it is easier to replace the carbon brush, the control is relatively simple, the motor runs smoothly and the safety factor is high.

So by comparison, it is more advantageous than brushed motor in terms of performance using brushless motor. You can choose the right brush motor or brushless motor according to your needs.
