HV STATOR TEST BENCH

HV Stator Test Bench is an on-line testing machine developed to test stator coils used to

engage clutches in automobile AC compressors. Main Features of the machine are:

 Fully PC based system, with NI Data acquisition cards & Lab VIEW software.

 Conducts 3 standard tests to check the quality of coil.

 Continuity & coil resistance test, checks the current drawn by coil with set limits.

 Insulation resistance test @ 600V AC - 1000V AC to check insulation quality of coil.

 High voltage layer short test @ 1500 V DC to check for any internal layers short or

turns present in coil, by comparing acquired ringing waveform developed from coil

under test with the master coil.

 “OK” & “NG” output after performing all tests and auto stamping on coil.

 Data logging for every coil tested during each shift for analysis point of view.
