How to maintain the electric car motor?

The motor is one of the four major parts of an electric vehicle, and is the power mechanism of an electric vehicle. Its performance has a direct impact on the performance of the electric vehicle, so it must be maintained and maintained. So, how to maintain the electric vehicle motor? 　　 1. Detect the degree of wear of the electric vehicle brush and commutator. Generally, the brush should be replaced when it is worn to 4~5mm away from the lead wire, and should be replaced when the commutator surface depth is greater than 0.5mm. Regardless of the degree of wear, the brushes and commutators should be replaced regularly (usually two years) for the motors in normal use.　　2. Regardless of whether it is a brush electric vehicle motor or a brushless electric vehicle motor, excessive input current will affect the performance. The voltage of the motor is supplied through the controller. The aging of the electronic components in the controller will cause the current input to the motor to increase. Therefore, the controller must be checked and replaced if necessary.　　3. Regularly lubricate the gears, bearings and deceleration parts of the electric vehicle motor. If the gears and bearing inner and outer jackets are worn too much, the anti-vibration plate is deformed, the spring performance is reduced or broken, the controller should be replaced.　　 4. Pay attention to frequently charging the battery of electric vehicles to keep the battery at sufficient voltage to prevent the motor from heating due to insufficient voltage and accelerate the aging of the electric vehicle motor.　　 The above is the maintenance method of the electric vehicle motor, I hope it will be helpful to everyone!
