Motor Factory Online Test Bench
The online test bench at the motor factory utilizes an industrial control computer for centralized management, enabling the completion of all test items with a single wiring setup. This comprehensive system integrates multiple measurements, including power frequency withstand voltage, grounding resistance, motor speed, and no-load tests. It boasts rapid test speeds, high precision, user-friendliness, and outstanding reliability. Additionally, it automatically analyzes and assesses the test outcomes. The system features robust data management capabilities, offering statistical analysis, storage, and printing of yearly, monthly, and daily reports. All motor parameters can be preset for streamlined testing.
Key Features:
1. Test Items: DC resistance, insulation resistance, turn-to-turn test, withstand voltage test, no-load test, blocked rotor test
2. DC Resistance: Measures motor winding resistance with high accuracy.
3. Insulation Resistance: Assesses insulation resistance between phase wire and housing to ensure safety and compliance.
4. Inter-turn Test: Detects inter-turn and inter-layer short circuits, poor insulation, and deviations in motor or transformer coils.
