Air Tightness Test checks the sealing performance of motor housing, end caps and wire terminals to block water, dust and moisture inside the motor, a key measure to meet IP waterproof standards.

Our Testing Process
We adopt positive pressure holding test for all finished motors. Seal all openings of the motor, inject compressed air and keep constant pressure for specified time.
Technicians monitor pressure drop; unqualified products will be resealed and retested. 10% of products are randomly sampled for immersion air tightness test.

What’s the Benefit?
· Prevent internal coil short circuit caused by water ingress.
· Adapt to wading, muddy and rugged off-road environments.
· Reduce failure rate and extend the overall service life of motors.
