Motor stator test system
The motor stator test system utilizes an advanced industrial control computer for centralized control. With a single wiring setup, it swiftly conducts comprehensive testing of national and enterprise mandatory inspection parameters such as power frequency withstand voltage, insulation resistance, inter-turn insulation, DC resistance, and rotor steering. This high-precision system ensures rapid testing, ease of operation, and outstanding reliability, automatically analyzing and judging the results. Additionally, it offers robust functionalities for statistics, storage, and printing of yearly, monthly, and daily reports. All testing parameters can be preset, enhancing both efficiency and accuracy.
Key features:
1. Test items: DC resistance, insulation resistance, turn-to-turn test, withstand voltage test, motor steering test, inductance test
2. DC resistance: Accurately measures the resistance of the motor winding.
3. Insulation resistance: Tests the insulation resistance between the phase wire and the shell.
4. Inter-turn test: Detects inter-turn and inter-layer short circuits, poor insulation, and out-of-tolerance conditions in motor or transformer coils.
5. Withstand voltage test: Measures the leakage current between the stator winding and the shell, with programmable control for accurate voltage regulation, managed via computer.
6. Motor steering: Determines the direction of the magnetic field rotation.
7. Inductance test: Measures the inductance of the motor coil.
8. Power supply: AC220V±15%, 50Hz±2 Hz (system working power supply)
9. Operating environment: Optimal working temperature range of 0~40 °C.
10. Working humidity: Maintains performance in environments with humidity ≤70%.
11. Streamlined operation: All tests are completed in one clamping.
12. Advanced control: All testing processes are microcomputer-controlled for precision.
