How to connect the motor wires of electric vehicles?

These pictures are all step by step according to the pictures. 1. Before installation, look for thick black, thick red and thin red wires, three positive and negative electrodes and lock wires, and three phase wires, namely thick yellow, thick green and thick blue Hall wires. Then connect the lines of corresponding colors.

2. Next, find a three-speed line connection. Generally, if the three-speed line is high, medium and low, we only need to adjust the positions of the three lines to know that it is normal.

Connect three speeds. Let's find the instrument line. Sometimes, after the instrument cable is connected, our on-board instrument will not move. We can directly connect the instrument wire coming out of the car to any one of the three motors, yellow, green and blue, and see which one works.

Before connecting the controller, make sure to disconnect the battery bus, that is, the air switch. If there is no or uncertainty, unscrew the screws and wires of any battery first, so as to avoid accidental short-circuit fire or wrong wiring to burn the controller.

Then, if there is a wiring board when the positive and negative electrodes are connected, try to put the positive and negative electrodes at the two ends of the wiring board to prevent the wiring screws from being short-circuited and burned. (This applies when there is no circuit breaker).

Hall is positive or negative, which means that the motor has a phase angle of 60, and no positive or negative is a phase angle of120. You can connect the positive and negative poles of the three Halls in parallel with the red and black thin wires in the motor lead-out wire (pay attention to insulation) and connect the signal wires of the three Halls with the yellow, green and blue thin wires in the motor lead-out wire (pay attention to insulation).
