Notes and use:
*DC motor speed controller input is DC, not directly connected to AC power, otherwise it will burn.
*You can not reverse the positive and negative DC power supply, otherwise it will damage the governor.
*Motors, regardless of positive and negative, when the running direction is inconsistent with the expectations, the direction can be changed by adjusting the order.
*Adjusting potentiometer knob to change the converter output duty cycle, thus changing the motor speed.
