Leak test (water detection) of electric vehicle motor

With the continuous rise in oil prices, new energy vehicles are gradually in the sight of consumers. And electric cars are powered by electricity. Electrical energy is made by the motor of a car that converts electrical energy into mechanical energy or converts mechanical energy.

If the air tightness of the motor is not well done, it is easy to affect the driving safety and road safety.

Today we share a case about the motor air leak tester.

Testing equipment: HC classic series air leak tester

According to the structure and shape of the motor, we choose the Seald Component test type and Volume to determine the finished product, customized the supporting tooling and fixtures.

Put the motor into the fixture and fix it, select the set program, and press the start key. The pre-fill time is 5s, and the fixture time is 5s. During this period, the equipment inputs a certain amount of air pressure, monitors a certain amount of time, and calculates the volume change through the formula set in the instrument. If the volume does not exceed 400ML, it is determined that the product has no max leak. At this time, carry out the next step of micro leakage test and start filling. After 8s, ensure that the air pressure in the chamber reaches 15kPa, stop and enter the pressure stable stage. After 12s, start the test. After 5s, the instrument judges whether the leak value exceeds 10Pa. If not, it indicates that the tested product is qualified.
