Motor stator test system
The motor stator test system integrates advanced industrial control computers to ensure centralized control of all testing parameters. By utilizing a single wiring setup, it efficiently and accurately detects mandatory national and enterprise inspection items, including power frequency withstand voltage, insulation resistance, inter-turn insulation, DC resistance, and rotor steering. This system boasts rapid testing speeds, unparalleled precision, user-friendly operation, and robust reliability. It further enhances productivity by automatically analyzing and judging test results, as well as offering extensive functions for statistical analysis, storage, and report printing on yearly, monthly, and daily bases. Users can preset all motor parameters for comprehensive 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: Accurately measures the resistance of motor windings.
3. Insulation resistance: Evaluates the insulation resistance between phase wire and shell.
4. Inter-turn test: Detects inter-turn and inter-layer short circuits, inadequate insulation, and coil deviations in motors or transformers.
5. Withstand voltage test: Measures leakage current between stator winding and shell, with computer-controlled voltage regulation.
6. Motor steering: Accurately determines the magnetic field's rotation direction.
7. Inductance test: Precisely 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: 0~40°C.
10. Working humidity: ≤70% for optimal performance.
11. All tests are seamlessly conducted in a single clamping.
12. Microcomputer controls all testing processes for enhanced accuracy and efficiency.
