The motor leaves the factory online test bench
The online test bench of the motor factory utilizes an advanced industrial control computer for centralized management. This cutting-edge system allows for seamless completion of all testing items with a single wiring setup. It integrates a diverse range of measurements including power frequency withstand voltage, grounding resistance, motor speed, and no-load tests. Boasting rapid test speeds, unparalleled precision, user-friendly operation, and exceptional reliability, the system also provides automatic analysis and judgment of test results. Moreover, it features comprehensive functions for statistics, storage, and printing of yearly, monthly, and daily reports. All motor parameters can be preset, enhancing the efficiency and accuracy of the testing process.
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: Precisely measures the motor winding resistance to ensure optimal performance.
3. Insulation resistance: Accurately tests the insulation resistance between the phase wire and the casing.
4. Inter-turn test: Evaluates for inter-turn and inter-layer short circuits, poor insulation, and out-of-tolerance conditions in motor or transformer coils.
5. Withstand voltage test: Measures the leakage current between the stator winding and the casing under high voltage. Features program-controlled voltage regulation, operable via computer.
6. No-load test: Assesses voltage, current, power, power factor, and frequency of the motor under no-load conditions (applicable for both single and three-phase motors).
7. Stall rotor test: Measures voltage, current, power, power factor, and frequency under motor stall conditions (motor's instantaneous start), suitable for both single and three-phase motors.
8. Power supply: AC220V±15%, 50Hz±2 Hz (system operating power supply)
9. Operating environment: Ideal working temperature range from 0~40 °C
10. Working humidity: Maintain at ≤70% for optimal performance.
11. Single wiring setup completes all tests.
12. All test processes are managed by an advanced microcomputer system.
