Precautions
The DC motor governor input is DC, and it cannot be directly connected to AC power, otherwise it will burn out.
Do not reverse the positive and negative terminals of the DC power supply, otherwise the governor may be damaged.
The motor can be positive or negative. When the running direction is inconsistent with the expectation, the direction can be changed by adjusting the line sequence.
Adjusting the potentiometer knob changes the governor output duty cycle and the motor speed changes.
