Test item and Techenical Specification:

1. 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)

2.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%

3. Insulation Resistance

Test condition: DC 500V

Range : 10MΩ~2000MΩ

Tolerance: 10MΩ~200MΩ ±3%

Above 200 MΩ, the tolerance is negligible

4. Polarity test

Testing 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.

5. 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%
