How to measure the quality of brushless motor in electric vehicle?

Answer:

Measure the motor with a multimeter. If there is a direct current resistance passage, there is no disconnection,Then, turn the motor on both ends of the motor by means of the multimeter voltage register

Hello,Measure the motor with a multimeter. If there is a direct current resistance passage, there is no disconnection,Then, turn the motor on both ends of the motor by means of the multimeter voltage register,Since the motor rotates to produce a induced voltage, the meter should have a voltage indication,The faster the rotation, the higher the voltage, the electrical performance of the motor can be no problem.

Since the motor rotates to produce a induced voltage, the meter should have a voltage indication,The faster the rotation, the higher the voltage, the electrical performance of the motor can be no problem.
