? PWM signal is generally used to drive brushless electrical modulation.
1. The use of PWM (pulse width modulation) signal drive is because the PWM signal can control the current size, thus controlling the motor speed and direction.
By adjusting the duty cycle of the PWM signal, the control effect of acceleration, deceleration and braking can be achieved. In addition, PWM signals are easier to transmit than analog and digital signals and can be generated directly using digital chips, simplifying the complexity of circuit design and control systems. 3. The brushless electromechanical modulation can also control the response speed and torque output of the motor according to the frequency of the PWM signal to meet the needs of different application scenarios. Summary: Therefore, the PWM signal is used to drive the brushless electromechanical modulation because the PWM signal is flexible, easy to transmit and adjustable, and can meet the precise control of the motor speed, direction and output.
Controlling brushless modulation requires sending PWM (pulse width modulation) signals to it. The following are the basic steps to control brushless power modulation:
