The Motor Factory Online Test Bench
Our state-of-the-art online test bench for motor factories leverages an industrial control computer for centralized operations. This highly integrated system allows completion of all testing items with a single wiring setup, encompassing power frequency withstand voltage, grounding resistance, motor speed, and no-load tests. Enjoy rapid testing with impeccable precision and user-friendly functionality, while relying on its robust reliability. The system automatically analyzes and evaluates test results, and offers comprehensive statistical, storage, and reporting functions on yearly, monthly, and daily bases. All motor parameters can be preset for streamlined testing.
Key Features:
1. Comprehensive Test Items: DC resistance, insulation resistance, turn-to-turn test, withstand voltage test, no-load test, blocked rotor test.
2. DC Resistance: Precisely measure the resistance within motor windings.
3. Insulation Resistance: Accurately assess the insulation resistance between phase wire and shell.
4. Inter-turn Test: Diagnose inter-turn and inter-layer short circuits, insulation deficiencies, and non-conformance in motor or transformer coils.
5. Withstand Voltage Test: Measure the leakage current between stator winding and shell, with program-controlled voltage regulation, also manageable via computer.
6. No-load Test: Evaluate motor voltage, current, power, power factor, and frequency under no-load conditions (compatible with single and three-phase motors).
7. Stall Rotor Test: Assess motor voltage, current, power, power factor, and frequency during stalled rotor conditions (motor instantaneous start), suitable 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 within a temperature range of 0~40 °C.
10. Working Humidity: Maintains efficiency in environments with humidity levels ≤70%.
11. Single wiring setup completes all tests.
12. Fully automated testing processes managed by microcomputer.
