Motor Stator Test System
The motor stator test system leverages an industrial control computer for centralized management, enabling all test items to be completed with a single wiring setup. This advanced system swiftly and accurately detects parameters in compliance with national and enterprise mandatory inspection standards, including power frequency withstand voltage, insulation resistance, inter-turn insulation, DC resistance, and rotor steering. Its standout features are rapid test speeds, exceptional precision, user-friendliness, and robust reliability. The system automatically analyzes and evaluates test results, and offers comprehensive functionalities for statistical analysis, storage, and printing of yearly, monthly, and daily reports. Pre-set all motor test parameters for seamless operations.
Key Features:
1. Test Items: DC resistance, insulation resistance, turn-to-turn test, withstand voltage test, motor steering test, inductance test
2. DC Resistance: Measure the resistance of the motor winding resistance with precision.
3. Insulation Resistance: Assess the insulation resistance between the phase wire and the motor casing.
4. Inter-Turn Test: Identify inter-turn and inter-layer short circuits, insulation failures, and parameter deviations in motor or transformer coils.
5. Withstand Voltage Test: Evaluate the withstand voltage leakage current between the stator winding and the casing. The process is program-controlled, with computer-regulated voltage adjustments.
6. Motor Steering: Determine the magnetic field's rotational direction with accuracy.
7. Inductance Test: Precisely measure the inductance of the motor coil.
8. Power Supply: AC220V±15%, 50Hz±2 Hz (system working power supply)
9. Operating Environment: Optimum working temperature of 0~40°C.
10. Working Humidity: Maintains efficiency at ≤70% humidity.
11. Single Clamping: All tests are completed with one clamping setup.
12. Microcomputer Control: All testing processes are governed by a microcomputer for precise control.
