Dynometer BLDC Motor Stator Tester DC Resistance Inductance Surge Isolation Hi-Pot Rotation WIND-DTS-300

 

 

 

(1) Stator tesing machine competitive advantages

 

     1. Testing Items Modular design,

 

         Each testing item including DC resistance,Inductance test,Surge Test, Insulation Resistance, 

 

         Hi-pot was modularized to a separate testing circuit board.

 

      2. This testing machine were delivered 15pcs to 20pcs every month for motor manufacturers.

 

 

 

(2) Test Items

 

 

 

1. DC resistance test (include 3 phase balance test,phase equilibrium test)

 

Test range: 0.001Ω--1000Ω

 

Test loop: maximum 4 loop (expandable)

 

Repeat Test accuracy: ≤±0.5%

 

Test method :Four points,with auto correctting ambient temperature function

 

Or Infrared sensor temperature compensation (Optional)

 

Can eliminate temperature-induced changes in resistance

 

 

2. Inductance test

 

Test range:0.1µH – 999H

 

Test loop: maximum 4 loop (expandable)

 

Repeat Test accuracy: ≤±1.0%

 

Test method :Four points ensure the accuracy

 

 

3. Surge test

 

Pass high voltage between phases

 

Test condition: AC 100V-3000V adjustable

 

Pulse peak :0.5msec

 

Sampling frequency:0 - 20MHz

 

Test loop: 4 loop

 

Repeat Test accuracy:< ±2.5%

 

Judging method:By area difference(Sensitive to inductance and energy loss)

 

Standard waveform is White,OK waveform is Green, NG waveform is Red

 

 

4. Insulation Resistance

 

Test condition: DC 500V / 1000V
