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
