Motor stator test system
The motor stator test system leverages a state-of-the-art industrial control computer for centralized operation, allowing all testing procedures to be completed with a single wiring setup. This advanced system efficiently measures and analyzes critical parameters for both national and enterprise-level mandatory inspections, including power frequency withstand voltage, insulation resistance, inter-turn insulation, DC resistance, rotor steering, among others. Offering rapid test speeds, high precision, user-friendliness, and exceptional reliability, it automatically analyzes and judges test results. Additionally, it features comprehensive functions for statistical analysis, storage, and printing of annual, monthly, and daily reports. All motor parameters can be pre-set for seamless testing.
Key features:
1. Test items: DC resistance, insulation resistance, turn-to-turn test, withstand voltage test, motor steering test, inductance test
2. DC resistance: precisely measures the resistance of the motor winding resistance
3. Insulation resistance: evaluates the insulation resistance between the phase wire and the shell for superior safety
4. Inter-turn test: identifies inter-turn and inter-layer short circuits, poor insulation, and out-of-tolerance conditions in motor or transformer coils
5. Withstand voltage test: assesses the withstand voltage leakage current between the stator winding and the shell, with programmable control over the voltage which can be regulated via computer
6. Motor steering: accurately determines the direction of the magnetic field rotation
7. Inductance test: measures the inductance of the motor coil with high accuracy
8. Power supply: AC220V±15%, 50Hz±2 Hz (system operational power supply)
9. Operating environment: optimal working temperature range of 0~40 °C
10. Humidity conditions: operational in working humidity levels of ≤70%
11. All tests are seamlessly completed in a single clamping operation.
12. The entire testing process is microcomputer-controlled for enhanced precision and efficiency.
