How to check the controller and motor of electric vehicle?
Five plug together is to go to the motor Holzer components, red and black for Holzer, positive and negative 5V or so. There are turn signals are three leads, each other for about 3V, in there to go to the headlights, speakers are power supply. It is necessary to measure its resistance when it is not connected. Different types of resistance vary.
When the brushless controller of the two wheeled electric vehicle is powered on, the input and output voltage of each lead is detected. The two is a thick line power line 48V, three RGB thick line is the main line voltage to the motor is 48V
The motor is checked in the case of power failure. The test followed by Holzer's positive and negative pole, the other one followed by the other three pen root sequence line. They have the same resistance, which proves that Holzer is good. RGB three phase line resistance on the motor is the same, different power of different motor resistance.In a word, check the voltage and check the resistance when the power is off.
