    How do the positive and negative poles of a DC motor meet?

    The two wires of the DC motor are one positive and one negative. Generally, the red wire is the positive wire and the black wire is the negative wire. It can be directly connected to the positive and negative ends of the power supply. If it is a permanent magnet motor, the positive and negative exchange will change the steering. The reverse connection of the series motor will not change the steering.

    If the direction of rotation of the motor is not what we need, you can reverse the connection of the positive and negative poles, and the direction of rotation can be changed. The speed is the same, and it has no adverse effect on the motor. It can be connected to the DC power supply through the switch.
