| High testing efficiency motor stator automatic tester |
Motor stator test system
The motor stator test system employs an industrial-grade control computer for centralized command, enabling comprehensive testing through a single wiring setup. This efficient system swiftly evaluates mandatory national and enterprise parameters such as power frequency withstand voltage, insulation resistance, inter-turn insulation, DC resistance, and rotor steering. Boasting rapid test speeds, exceptional precision, user-friendly operation, and outstanding reliability, it automatically analyzes and interprets test outcomes. Additionally, it offers detailed statistical, storage, and printing capabilities for yearly, monthly, and daily reports, with all motor test parameters preset for streamlined examination.
Key features:
1. Test items: DC resistance, insulation resistance, turn-to-turn test, withstand voltage test, motor steering test, inductance test
2. DC resistance: Measures the resistance of the motor winding resistance
3. Insulation resistance: Assesses the insulation resistance between the phase wire and the casing
4. Inter-turn test: Diagnoses inter-turn and inter-layer short circuits, poor insulation, and non-compliance in motor or transformer coils
5. Withstand voltage test: Evaluates the leakage current between the stator winding and the casing, with program-controlled voltage regulation managed by computer
6. Motor steering: Determines the rotation direction of the magnetic field
7. Inductance test: Gauges the inductance of the motor coil
8. Power supply: Operates on AC220V±15%, 50Hz±2 Hz (system working power supply)
9. Operating environment: Functional temperature range of 0~40°C
10. Working humidity: ≤70%
11. All tests are completed in a single clamping.
12. All testing processes are microcomputer controlled.
