High Integrated Stator Testing System Of Air Conditioner Indoor Motor
1. Test object: stator of air conditioner motor
2. Test items
Insulation resistance, surge, winding resistance, AC Hipot, direction of rotation
3. Function description
3.1 Built in industrial computer(IPC), Linux operating system, professional software, clear interface
3.2 Standard equipped with yellow, green and red indicating light.
3.3 Test the environment temperature in real time during the DC winding resistance test. And the
resistance testing result will convert to the standard temperature value automatically.
3.4 The left station and right station works alternatively.
3.5 The operators can select test items as required.
3.6 Available selected motor model ≥1000.
3.7 The parameters range for each type of motor can be entered and saved. The inductance and
resistance test has the function of setting and displaying the unbalanced degree.
3.8 Two options are available if the stator fails the test: “continue to test” and “stop the test”. If the stator
fails the ending resistance test, the test will be stopped until testing all the other items.
3.9 The testing data can be saved in the database, including the specific test result for each tested stator.
3.10 The testing data can be exported in the format of Excel via USB interface.
