| Three-phase motor stator tester DC resistance test |
Motor stator test system
The motor stator test system is a state-of-the-art solution that employs an industrial control computer for centralized management. This innovative system allows for the completion of all tested items with a single wiring setup, enabling the rapid detection of mandatory inspection parameters set by national and enterprise standards, including power frequency withstand voltage, insulation resistance, inter-turn insulation, DC resistance, and rotor steering. Notable benefits include exceptional test speed, unparalleled precision, user-friendly operation, and superior reliability, with automatic analysis and judgment of test results. Additionally, the system features comprehensive functions for the statistics, storage, and printing of yearly, monthly, and daily reports. All motor test parameters can be preset 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.
3. Insulation resistance: Assesses the insulation resistance between the phase wire and the casing.
4. Inter-turn test: Detects inter-turn and inter-layer short circuits, poor insulation, and tolerance issues within motor or transformer coils.
5. Withstand voltage test: Evaluates the leakage current between the stator winding and the casing, featuring programmable control for voltage adjustments, and compatibility with computer-based voltage regulation.
6. Motor steering: Determines the rotational direction of the magnetic field.
7. Inductance test: Measures the inductance of the motor coil with high precision.
8. Power supply: AC220V±15%, 50Hz±2 Hz (system operational power supply)
9. Operating environment: Optimal performance at temperatures ranging from 0 to 40 °C.
10. Working humidity: Maintains functionality at humidity levels ≤70%.
11. All tests are executed with a single clamping setup, streamlining the process.
12. All testing processes are meticulously controlled by a microcomputer, ensuring consistency and accuracy.
