1. Model No.: ND-ST023
2.The stator testing panel equipment machine is applied to
integrated test varieties of compressor stator in refrigerator, air
conditioner and heater etc.
3. Each test items could be on or off randomly.
4.The testing data will show on the screen.
This series of stator testing equipment is applied to integrated
test varieties of compressor stator in refrigerator, air
conditioner and heater etc. Its LCD shows all technical data which
obtained by industrial control computer, which check and verify the
quality of testing stators.

Test item and Techenical Specification:
1.Cooling state resistance test
Four points, with auto correctting ambient temperature function,
the standard temperature can be set, wire connection according to
Test range: 1Ω--200Ω
Test tolerance: ±1%
Pass high voltage between core and winding
|Test condition||AC 0-3000V adjustable.|
|current leakage range||0.1-10mA|
3. Insulation Resistance
|Test condition||DC 500V|
Above 200 MΩ, the tolerance is negligible
4. Turn to Turn Insulation
Test condition: Taking a qualified stator as the standard sample,
and save its test curve and data in computer. Then comparing the
values of standard one and the to-be-tested stator, calculating the
area and the relative error value of frequency, and then figure out
the upper limit value of relative error value.
Pulse voltage peak value: 500V-3000V
Pulse peak value tolerance : ±5%
Criterion value setting: conclude as per the percentage of
S and f, setting range is: 1%-99%
5. Polarity test
Test condition: Electrify the motor stator DC current, judge the
polarity direction of the stator by Hall element. Criterion value setting: Alert when the direction of polarity is
different from the setting.
