MICROTEST MT-6913 Motor Stator Testing System integrates the Interlayer Short-Circuit Tester (6913), the High Voltage Withstand Tester (7605), and the LCR Tester (6365), with the 6913 serving as the main controller. It is capable of setting up all measurement parameters and provides 13 test channels. The external PC software allows for real-time data retrieval from the 6913, generating reports, or directly uploading test results to a database.

This all-in-one integrated system covers safety compliance, high-voltage insulation, and coil interlayer short-circuit testing for motor stators. It can measure motor stator polarity (rotation test) using precise four-wire resistance measurement technology. Additionally, it supports three-phase current balance testing (optional). The system can be equipped with PC connectivity software for data storage and can be configured with PLC control. Customized test fixtures can be provided for specific customer stators. Furthermore, it offers an optional LCR Meter for measuring the stator’s inductance values with a test frequency range of 10Hz to 200kHz, supporting three-phase balanced inductance testing.

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. Show by percentage Analysis the power loss by this data.
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.
