There are many differences between brushed motors and brushless motors. As the names suggest, brushed motors have carbon brushes, while brushless motors do not. To clarify the differences, the editor of China Transmission Network will now provide a simple analysis!
1. Service life:
Brushless motor: can work continuously for about 20,000 hours, with a typical service life of 7-10 years.
Brushed motor: can work continuously for about 5,000 hours, with a normal service life of 2-3 years.
2. Usage effect:
Brushless motor: It operates at a high speed of 90-95m/s and performs well.
Brushed motors: Their operating speed and drying time are much lower than those of brushless motors.
3. Regarding energy conservation:
In comparison, the power consumption of a brushless motor is only 1/3 that of a carbon brush.
4. Noise and service life
Brushed motors are much noisier than brushless motors, and as the carbon brushes wear out in the future, the noise of brushed motors from brushless motor manufacturers will increase, while brushless motors will not be affected.
5. In terms of maintenance
When a brushed motor wears out, not only the carbon brushes need to be replaced, but also surrounding accessories such as the rotating gears. This is significantly more expensive. Most importantly, the overall functionality will be affected.
Typically, brushless motors use electronic commutation instead of mechanical commutation, which is technically superior to brushed motors. Furthermore, brushless motors lack gears or reduction gears, thus reducing the unreliability caused by motor wear. Within a certain current range, their efficiency is higher than that of brushed motors. Brushless motors operate almost silently and have a lifespan exceeding 10 years.
Of course, brushless motors are more expensive, and their controllers are more complex and costly. However, compared to brushed motors, brushless motors are increasingly becoming the mainstream in the market.
In actual production, brushed DC motors, being high-speed motors, have small gear teeth that are prone to wear. Brushless motors, however, offer superior power and climbing ability. They eliminate the hassle of replacing carbon brushes every two to three years. However, controlling a brushless motor requires high precision, and the controller is more expensive. Conversely, while brushed DC motors do require carbon brush replacement, this process is very easy, motor control is relatively simple, and the motor operates smoothly with a high safety factor.
In comparison, brushless motors offer superior performance compared to brushed motors. You can choose the appropriate brushed or brushless motor based on your needs.
The above explains whether brushless motors or brushed motors are easier to use. We hope this information is helpful so you can buy the motor product you want.
