Car Wiper Motor Waterproof Film

Analysis of XINZHENPIN® Car Wiper Motor Waterproof Film

Although the wiper motor sparrow is small, all the viscera, is a more complex system. It is usually composed of electric housing, rotor, reducer, output shaft, cover plate and other parts of the assembly. Throughout its life, its main job is to work with water.

When the wiper motor is working, the internal temperature can reach 90 degrees Celsius. When it stops working, it quickly falls back to the room temperature of about 30 degrees Celsius. The resulting pressure difference between the inside and outside of the motor will draw external moisture into the motor, causing motor failure. Therefore, the sealing requirements of the motor are relatively high. The waterproof grade of the general wiper motor is IP4K. The rain test requires the flow rate of 15L/MIN and the water pressure of 400KP.

To ensure that the above requirements are met, all wiper suppliers perform a 100% air tightness check after the motor is assembled to ensure that the motor is well sealed. Keep an eye on this if you are conducting an on-site supplier audit.

The repeated "heating and cooling" of the motor causes the whole wiper motor to be constantly under negative pressure.In the process of after-sale use, the waterproof function of the motor is constantly declining, and eventually the rain will enter the motor from the weakest place.
