The difference between AC brush motors and AC brushless motors
Ac Brushless motor is new product, its life performance is better than AC brush motors’. But its control circuit is more complex, and the aging of the components screening requirements are more stringent. Although the motor’s life is long, but the control circuit is easy to broke. Therefore, the choice of Ac brushless motor MUST go through rigorous reliability tests to ensure quality.
In the actual production process, because brush DC motors are high-speed motor, the gear teeth is small and easy to wear, but the power is large and the climbing ability is strong. While brushless DC motor eliminates the trouble of replacing the carbon brushes in two or three years. However, it is requiring high precision during the process of brushless motor control, Moreover, brushless motor controller’s price is very expensive. In contrast, brush DC motor has more advantages than brushless motor.
