Notes:
The input of the DC motor governor is DC power, and it is not directly connected to AC power (for example: household 220V AC), 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.
