As the power source of new energy vehicles, the quality of motor determines how far new energy vehicles can go. New energy electric vehicle is mainly composed of motor drive system, battery system and vehicle control system. Motor drive system is the part that directly converts electric energy into mechanical energy. Motor determines the performance index of electric vehicle.

New energy automobile motor waterproof inspection fixture

As the core drive system of new energy vehicles, electric motor is widely used,In the face of the harsh environment, once the motor water, it will affect the vehicle performance. Therefore, the motor of new energy vehicle must adopt waterproof design,Only from the motor shell to increase the sealing will increase the cost of motor manufacturing, and the motor after maintenance waterproof sealing is worse, so it needs a new methodAir tightness test is used to test the waterproof performance of the motor.

New energy vehicle motor air tightness and waterproof inspection fixture

According to the requirements of customers, we need toNew energy vehicle motorconductIP68Waterproof gradeThe following equipment and solutions are used in the test:

Equipment used: HarrisHCClassic series of airtight waterproof testing equipment

Solution: adopt indirect test method to test pressure70KPA，Inflation time10S，holding time 10S, test time8S, upper leakage limit0.05KPA。The test fixture is designed according to the structure of the motor. The fixture is used to seal the whole motor. The instrument monitors the air pressure inside the mold through the process of inflation, voltage stabilization and testing, and detects the leakage of the motor. The system automatically judges the test results according to the set parametersOKorNG。
