MICROTEST MT-6920 Motor Rotor Testing System combines the Interlayer Short-Circuit Tester (6920), the High Voltage Withstand Tester (7605), and the Multi-Channel Control Box (6908), with the 6920 serving as the main controller. It allows for the configuration of all measurement parameters and provides 24/48 test channels. The external PC software enables direct real-time access to test results from the 6920, as well as report generation and direct uploading of test results to a database.
MT-6920 Motor Rotor Testing System offers 24/48 channel testing capability for measuring the welding resistance of motor rotors. It integrates safety compliance, high-voltage insulation, and coil interlayer short-circuit testing into one system. It supports remote programming and data storage via PC connectivity software and can be equipped with PLC control. Customized test fixtures can be provided for rotor testing according to customer specifications.

| Total area comparison | When layer short happened, the loss of power on coil increase, the resonance damping coefficient increase, resonance amplitude decrease, the total area decrease. These are the basic parameters we check layer short.
By calculating and comparing the deference of area between golden sample and DUT. |
| Differential area comparison | Add up the difference between normal wave and DUT wave call “ Area differential”. When layer short happened, the inductance reduce(similar the transformer). The wave phase change and the area differential also change. This will show “fail” on the instrument. However, the parameter might cause deviation because of the deviation of inductance, resonance phase shift. (Silicon steel product such as motor and traditional transformer is not suitable)By calculating and comparing the deference of area between golden sample and DUT. To determine the degree of waveform overlap. Compare the inductance by this. |
| Wave comparison | Set a acceptable wave range, if the DUT’s wave is in this range shows “pass” otherwise, “fail” This parameter can judge both amplitude and phase of resonance wave. This can increase the detection capability of layer short. |
| Corona comparison | In pulse test, the insulation defect will cause discharge and create corona. This function is able to count the times that corona happened base on the degree of deviation. Detect the discharge phenomenon on the coil. |
| Flat comparison | If the layer short happened, the waveform will tremble. Therefore, the instrument will quantize and compared it. |
