Description:

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

Test method:
Four points, with auto correctting ambient temperature function, the standard temperature can be set, wire connection according to buyer's requirement.

Test range: 1Ω--200Ω

Test tolerance: ±1%

2. Dielectricstrength

Pass high voltage between core and winding

Test condition: AC 0-3000V adjustable.

Voltage tolerance: ±3%

current leakage range: 0.1-10mA

Current tolerance: ±1%

Time : 1s~60s(software setting)

3. Insulation Resistance

Test condition: DC 500V

Range : 10MΩ~2000MΩ

Tolerance: 10MΩ~200MΩ ±3%

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.
