stator testing panel

Basic configuration 1. Tester Max dimension: 850(width)*950(depth)*1870(height), surface plastic blast, white color computer. Electric cabinet in good ventilation condition and mouse proof. 2. Two working position could rotary test. The height of working position is 790mm,working station dimension is 460(depth)*800(width) 3.

Computer system with CPU1.3G,internal save capacity 128M,harddisk 80G,15"colorful display screen 4. Connector and sampling circuit from Japan and U.S.A 5. Windows 2000 operation system 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. Dielectric strength 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.
