Home > product > Test System Photo Explanation This facility as an example of test jig for Rotor(Armature) Test has so many Air cylinders in the environs of segments, and it is possible to put Rotor on and down from the above. As occasion demands, it is manufactured in the form of having only 2 or 3 Air cylinders loaded in, accordingly it can be thought that Rotor rotates at every regular angle on every conversion of test steps. But because synthetic test time can increases, also operation error and trouble can occur frequently, the efficiency becomes much debased during its use. Explanation On rotor or Armature Test, in case of Brush type, Surge-Puncture-Resistance Test are important but also it must to be tested whether each and every segments of Commutator has a perfect Fusing conditions or not. This method, differently from Resistance Test, has to try to apply a great deal of a large current directly to each and every segment, and has to check the resistance condition at this time. For this test, the test jig of Rotor needs to have each one of Air cylinder for the purpose of applying current to each and every segment. Therefore it inevitably has a complicated composition but is necessary to improve a test speed and take a perfect test. Standard specifications Equipment working voltage AC110 V, 220 V, 50 ~ 60 ㎐ Test Item Freely set up as occasion demands. There is a difference according to the no. of segment. To test the perfect fusing state, test step increases that much. Therefore usually it requires 13∼14 sec. Dimensions Cabinet and Work table are as like Stator Tester of the side page but Test jig has more complicated composition. Control method : PLC control method and use of Magnet, H,V Reed Relay. Dimensions 　　Cabinet : W600, H1820, D800 ㎜ 　　Worktable : W600, H900, D600 ㎜ Test Item Surge Test Decides whether Layer Short, Pin hole, Corona occur or not between coils, also whether short and an alien substance intervention occur or not between segments. Puncture Test Confirms the dielectric strength between coil and core(or shaft) Resistance Test Divides segment of Commutator equally among three or four and confirms the settlement state of winding. Fusing Test To distinguish whether the contact between coil and segment is perfect or not, it is necessary to test and confirm each and every segment. Generally if Fusing test is carried out perfectly, test can be omitted.
