The DC brushless servo motor with stable motor performance adopts NdFe35 permanent magnet material with strong anti-magnetization ability. Low noise and vibration, high torque and fast dynamic response. Compact size, easy to carry and install.

PWM (Pulse Width Modulation) control of DC motors is a common method used to control the speed and direction of DC motors. The basic principle of PWM control is to control the average voltage of the electric servo motor by adjusting the duty cycle of the square wave, thus realizing the speed and direction control of the motor.

In PWM control, DSP and other microprocessors will generate a PWM signal, the duty cycle of the signal can be adjusted to control the average voltage of the motor. Specifically, when the duty cycle of the PWM signal is large, the average voltage of the motor draft, turn fast; when the duty cycle of the PWM signal is small, the average voltage of the motor is small.

When the duty cycle of the PWM signal is small, the average voltage of the motor is low and it turns slowly. By adjusting the duty cycle of the PWM signal, continuous speed regulation and precise control of the motor can be realized. In PWM control, it is also necessary to consider the polarity control of the motor. Generally speaking, by changing the phase or polarity of the PWM signal, the direction of rotation of the motor can be changed.
