As the power source of new energy vehicles, the quality of motors determines how far new energy vehicles can go.New energy electric vehicles are mainly composed of three parts: motor drive system, battery system and vehicle control system. The motor drive system is the part that directly converts electrical energy into mechanical energy. The motor determines the performance indicators of the electric vehicle.

New energy vehicle motor waterproof testingJig

As the core drive system of new energy vehicles, motorsThe environment it faces is relatively harsh. Once the motor gets water, it will affect the performance of the entire vehicle.Therefore, new energy vehicle motors must adopt a waterproof design.Simply increasing the sealing from the motor casing will increase the cost of motor manufacturing, and the waterproof sealing will be even worse after the motor is repaired, so a method is needed.Air tightness testingWay to test the waterproof performance of the motor.

New energy vehicle motor air tightness and waterproof testing fixture

According to customer requirements, it is necessary toNew energy vehicle motorconductIP68Waterproof levelFor testing, Hirays Technology used the following equipment and solutions:

Equipment used: HiraysHCClassic seriesAir tightness and waterproof testing equipment

Solution: Use indirect testing to test pressure70KPA，Inflation time10S，Stabilization time10S, test time8S, leakage upper limit0.05KPA。The test fixture is designed according to the structure of the motor, and the fixture is used to seal the entire motor. The instrument monitors the air pressure inside the mold through processes such as inflation, voltage stabilization, and testing to detect leakage of the motor. The system automatically determines the detection results based on the set parameters.OKorNG。
