Stator Vacuum Testing Machine For Household Air Conditioner Compressor
1. Introduction
1.1. Features: unique vacuum negative pressure technology, and the vacuum of environment (0~-90KPa)can be freely set, it is easy to find the failure of the coils under the negative pressure.
1.2. Vacuum test: The movement of free electrons will generate static electricity, in order to generate a large amount of static electricity, a lot of free electrons need to move, which can be achieved by increasing the friction area and friction speed.
1.3. Test items: surge, AC Hipot, rotation, DC winding resistance, insulation resistance

3. Performance
3.1. Built-in IPC, professional software, clean interface.
3.2. Yellow, green and red three-color indicating light.
3.3. The winding quality won’t be affected by the surge test, which takes the testing mode of undamaged capacitor impulse discharge.
3.4. In the process of DC winding resistance test, the machine test the ambient temperature in real time, and the resistance will be converted to that under standard temperature.
3.5. All the tests can be selected or unselected.
3.6. Testing parameters of each model can be entered and saved by the operator. Resistance unbalance degree can be set, displayed and judged by the machine.
3.7. Two options are available if NG appears: “continue to test” and “stop the test”. If NG occurs when testing the winding resistance, the test can be stopped after testing the three windings.
3.8. The statistical data can be founded on the test interface. All the testing data can be exported via the USB interface.
3.9. User permission settings to avoid the misoperation by operators.
