DC motor governor input is DC, can not directly connect to the AC (for example home 220V AC), otherwise, it will burn!
DC power supply positive and negative terminals do not reverse, otherwise, the governor may be damaged.
The motor can be positive or negative when the direction of operation and expectations do not match, you can adjust the line order to change the direction.
Adjust the potentiometer knob to change the governor output duty cycle, the motor speed changes.
