A quality breakthrough for a drive motor company

Project background:

During the mass production of its new generation of permanent magnet synchronous motors, a well-known domestic drive motor manufacturer faced the problem of product qualification rate fluctuations caused by leakage in the cooling system.

Technical challenges:

Traditional water detection methods are inefficient and may cause secondary damage to the motor.

Microleakage is difficult to locate accurately, and the average troubleshooting time exceeds 90 minutes

Unable to meet the detection rhythm requirements of high-speed production lines

Solution:

Deploy the Heris online helium mass spectrometry leak detection system, equipped with special docking tooling and automated transmission system, to achieve 100% online detection of the motor assembly.

Implementation results:

The detection accuracy rate has been increased to 99.95%, and the false positive rate has been reduced to less than 0.05%.

Troubleshooting time is shortened to less than 15 minutes, and efficiency is increased by 85%

Perfectly matches the rhythm of high-speed production lines, increasing production capacity by 25%

Annual quality cost reduced by approximately RMB 3.5 million
