The input voltage should be equal to the rated voltage of the motor. It is not possible to input 220V household electricity. 2. The input must distinguish between positive and negative polarity. 3, The motor can be divided into negative, when the running direction is inconsistent with the expected, you can change the direction by adjusting the motor wire sequence 1Adopt pulse width modulation for more stable operation 2Speed adjustment, potentiometer with switch 3The center distance of the mounting hole is 104mm, which is convenient for installation and removal. 4The speed range is 0%--100%, it has good control ability 5Suitable for wide voltage
