Refrigeration Compressor Motor Stator Winding Testing Machine
Stator Testing Machine For Compressor Motor Stator/Refrigerator/Air Conditioner Compressor Motor
1. Product: Stator testing machine
2. Tested product: compressor motor stator
3. Stator testing machine introduction
This testing machine can be used to test the stator of compressor motor for home appliance. The AC Hipot/high voltage/dielectric strength, insulation resistance, surge/impulse/layer short, winding resistance and direction of rotation can be tested at one-stop.
The testing machine comes with two test stations to ensure the efficiency of the production. All the tests mentioned above takes less than 8 second in total for one stator. Standard equipped with the three color alarm light to indicate the machine status.
