What are the advantages and disadvantages of brushless motors and brushed motors?
Next, a brief introduction.
Advantages of brushless motors:
1. Reliable performance, no wear and tear, and low failure rate.
2. It is a static motor with small no-load current.
3. Long life and low maintenance cost.
4. Low noise and smooth operation.
5. High efficiency and small size.
Disadvantages of brushless motors
1. There is slight vibration when starting at low speed.
2. The price is high and the controller requirements are high.
3. It is easy to form resonance phenomenon.
Advantages of brushed motors
1. The speed change is smooth and the vibration is almost not felt.
2. Low temperature rise and good reliability.
3. The price is low, so it is chosen by many manufacturers.
Disadvantages of brushed motors
1. Large friction and loss.
2. Low efficiency and low output power.
3. Carbon brushes are easy to wear, troublesome to replace, and have short life.
4. The operating current is large, and the motor magnets are easy to demagnetize, which reduces the life of the motor.
