Exploring Motor Stator Test System
For electrical safety and quality testing functions of motor stator coils
Paschen’s Law is an equation that provides the breakdown voltage, that is the voltage necessary to start a discharge or electric arc, between two electrodes in a gas as a function of pressure and gap length. Per Paschen’s Law, gas CIV (Corona Inception Voltage) is nearly proportional to the air pressure (p) at a fixed gap distance (d). Because of this, it is possible to detect winding defects at lower Hi-Pot and Impulse Winding test voltages under partial vacuum. This also makes it easier to find defects at less damaging energy levels, making it possible to not only judge that the device failed but to also fix the defect, because at lower discharge energy the gas discharge is more visible.
The Chroma 1920 test system can be used not just for electrical safety testing, but also for quality testing, as it provides complete functions for motor stator coil inspection. The Ls/Q (Quality factor) check enables the system to find defective coils which may run and look normal but become hotter than desired after assembled as a complete motor. The Rotation check is normally used to check that the winding connector assembly is correctly performing or not. The Chroma 1920 can also provide phase detection with an LCR Meter, Hall Sensor or general rotor rotation test options designed for this. We can provide swappable test fixtures to improve production speed. The operation software provides a user friendly test program editing interface and test results display, as well as record and file management to complete the system as the best choice for motor stator coil production and quality assurance testing.
