Car Generator Alternator Stator Testing Machine Quality Analysis WIND-DTS
(1) Competitive Advantages
Double position test in turn, the shortest test time can be up to 5 s/pc
(2) Testing item and accuracy
1. DC 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: 0.01Ω--1000Ω
Test tolerance: ±0.5%
2. Dielectric strength
Pass high voltage between phases
Test condition: AC 100V-3000V adjustable
Voltage tolerance : ±2.5%
current leakage range : 0.1-20mA
Current tolerance: ±1%
Time: 1sec～10sec(software setting)
3. Insulation Resistance
Test condition: DC 500V / 1000V
Range: 1MΩ～1000MΩ
Tolerance: ±2.5%
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: 100V-3000V
Pulse peak value tolerance: ±2.5%
Suitable for detection of small inductive stators
Criterion value setting: conclude as per the percentage of △S and △f, setting range is 1%-99%
5. Balance of resistance
Determine the balance of resistance between coils
