The customer applied the AIP stator vacuum test machine to realize the online full inspection of the compressor motor stator. Through years of research and development efforts, AIP realized the effective combination of the vacuum environment test time and the production cycle on the premise of ensuring the quality of the test. The degree can be set freely (0-99KPA) to improve the detection rate of defective products. The machine can realize electrical or parallel testing according to demand, and maximize the production cycle. This machine has been applied in batches in the compressor motor industry at home and abroad.
