The motor leaves the factory online test bench
The online test bench of the motor factory utilizes a state-of-the-art industrial control computer for centralized automation, ensuring all test items are seamlessly completed with a single wiring setup. This integration includes diverse measurements such as power frequency withstand voltage, grounding resistance, motor speed, and no-load tests. The system boasts unparalleled advantages of rapid test speeds, exceptional precision, user-friendly interfaces, and robust reliability. It not only automates the analysis and judgement of test results but also offers comprehensive functions for statistics, storage, and printing of yearly, monthly, and daily reports. Moreover, it allows for presetting all parameters of the motor under test for a streamlined 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: Measures the resistance of the motor winding resistance with high precision.
3. Insulation resistance: Evaluates the insulation resistance between the phase wire and the shell for safety compliance.
4. Inter-turn test: Detects inter-turn and inter-layer short circuits, poor insulation, and tolerance deviations in motor or transformer coils.
5. Withstand voltage test: Assesses the leakage current between the stator winding and the shell, with program-controlled voltage settings and computer-regulated voltage adjustments.
6. No-load test: Measures essential parameters such as voltage, current, power, power factor, and frequency under no-load conditions (compatible with both single-phase and three-phase motors).
7. Stall rotor test: Determines key metrics including voltage, current, power, power factor, and frequency during motor stall (instantaneous start), applicable to both single-phase and three-phase motors.
8. Power supply: Operates on AC220V±15%, 50Hz±2 Hz, ensuring consistent power for the system's functionality.
