How to test the quality of electric motors?
If normal, the motor control is good. In addition, the line of three thick points is the motor line. As long as there are many ohms resistance between the line and the line, and the difference of the resistance value is very small, the motor can be judged well.Is the answer satisfactory? Please adopt! Thanks!
Open the plug in the control and insert only the red and black wires. Connect to a multimeter. Use a DC voltage of 10 volts, and the red line is connected with the red one. Black, respectively, with three other lines, one at a time, turn the wheel with one hand, angle, the multimeter should have voltage, 4V and 0V change is normal, otherwise it is not normal, and the three are measured in the same way
The brushless motor has 5 control lines, the red line and the black line are the positive and negative pole of the three Holzer components in the motor, and the other three are the output of the three Holzer components.
