Introducing the cutting-edge Motor Factory Online Test Bench
The state-of-the-art online test bench of the motor factory features centralized control via an industrial control computer, enabling comprehensive testing through a single wiring setup. This system integrates various testing measurements, including power frequency withstand voltage, grounding resistance, motor speed, and no-load tests. Boasting rapid test speeds, high precision, ease of use, and robust reliability, it automatically analyzes and evaluates test results. Additionally, it provides functionalities for statistical analysis, storage, and printing of yearly, monthly, and daily reports. Comprehensive motor parameter presets ensure streamlined testing.
Key Features Include:
1. Comprehensive Test Items: DC resistance, insulation resistance, turn-to-turn test, withstand voltage test, no-load test, and blocked rotor test.
2. DC Resistance: Accurately measure the resistance of motor windings.
3. Insulation Resistance: Test the insulation resistance between phase wires and the motor casing.
4. Inter-Turn Test: Diagnose inter-turn and inter-layer short circuits, poor insulation, and tolerance issues in motor or transformer coils.
5. Withstand Voltage Test: Measure the leakage current between stator windings and the casing, with programmable control and computer-regulated voltage adjustments.
6. No-Load Test: Evaluate voltage, current, power, power factor, and frequency under no-load conditions for both single and three-phase motors.
7. Stall Rotor Test: Measure voltage, current, power, power factor, and frequency during motor stall rotor conditions (instantaneous start) for single and three-phase motors.
8. Power Supply: Operates on AC220V±15%, 50Hz±2 Hz (system working power supply).
9. Operating Environment: Optimal performance at temperatures between 0~40 °C.
10. Humidity Tolerance: Functions efficiently at working humidity levels of ≤70%.
11. First wiring execution completes all tests seamlessly.
12. Automated control of all testing processes via microcomputer.
