| Stator Winding Coil Test Bench |
Revolutionary Motor Stator Test System
The motor stator test system integrates an industrial control computer for centralized command. With a single wiring setup, it swiftly evaluates national and enterprise-mandated parameters, including power frequency withstand voltage, insulation resistance, inter-turn insulation, DC resistance, and rotor steering. This system boasts rapid testing speeds, exceptional precision, user-friendly operation, and robust reliability. It also autonomously analyzes and determines test outcomes, and offers comprehensive functionalities for statistical analysis, data storage, and report printing on yearly, monthly, and daily intervals. All motor parameters can be pre-configured for seamless testing.
Distinguished Features:
1. Comprehensive Test Items: DC resistance, insulation resistance, turn-to-turn test, withstand voltage test, motor steering test, inductance test.
2. DC Resistance: Accurately tests the resistance within the motor winding.
3. Insulation Resistance: Evaluates 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 motor or transformer coil deviations.
5. Withstand Voltage Test: Measures the leakage current between the stator winding and casing during voltage withstand, with programmable control and computer-guided voltage regulation.
6. Motor Steering: Determines the rotational direction of the magnetic field.
7. Inductance Test: Accurately measures the inductance levels of the motor coil.
8. Power Supply: Operates on AC220V±15%, 50Hz±2 Hz (system working power supply).
9. Operating Environment: Optimal performance within a temperature range of 0~40 °C.
10. Humidity Tolerance: Functions efficiently at working humidity levels ≤70%.
11. Integrated Testing: All evaluations are conducted with a single clamping.
12. Automated Control: All testing procedures are managed by a microcomputer.
