Reasons for electric vehicle motor pumping

As the power energy equipment for electric vehicles, electric motor motors can cause very serious problems in the event of pumping failures, resulting in electric vehicles not being able to drive normally, even in the course of driving, dangerous accidents due to pumping problems. Therefore, when it is detected that the motor cannot be used normally, it must be stopped and repaired in time. Do not use the motor with hidden troubles. So what is the cause of the pumping phenomenon in the motor is God? How to solve it?

 

1. The electric vehicle motor used for higher production cannot directly discharge the atmosphere. If the air is directly discharged, the pressure difference between the suction port and the exhaust port will be too large, so that the motor with high slip rate is overloaded.

 

2. When the electric vehicle motor is used, it is necessary to have a foreline pump. When the foreline pump is used to draw the pressure inside the system to a certain range, the overload phenomenon can be avoided.

 

3. Since the rotor of the electric vehicle motor is continuously turned over, the sucked gas is sucked from the air inlet into the space between the rotor and the pump casing, and then discharged through the exhaust port. Therefore, when the top of the rotor turns over the edge of the exhaust port and the space communicates with the exhaust side, since the gas pressure on the exhaust side is high, a part of the gas is returned to the space, so that the gas pressure is suddenly increased. When the rotor continues to shift, the gas is exhausted.

 

Therefore, when the electric motor motor has a pumping fault, it indicates that there is a serious fault in the internal parts of the motor. It is necessary to carry out maintenance operations in time to avoid the fault condition being aggravated. Otherwise, the motor will not be able to provide power energy, and the electric vehicle cannot drive. Users are bothered.
