The Motor Factory Online Test Bench
The online test bench at the motor factory is revolutionized with an industrial control computer for centralized control, enabling comprehensive testing with a single wiring setup. This advanced system integrates multiple measurements such as power frequency withstand voltage, grounding resistance, motor speed, and no-load tests. It boasts rapid testing speeds, exceptional precision, user-friendly operation, and outstanding reliability. Moreover, it automatically analyzes and evaluates test results, offering robust functions for statistics, storage, and printing of reports on a yearly, monthly, and daily basis. All motor parameters can be preset for seamless 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: Measure the resistance of the motor winding resistance with high accuracy.
3. Insulation Resistance: Assess the insulation resistance between the phase wire and the motor shell to ensure safety and performance.
4. Inter-turn Test: Detect inter-turn and inter-layer short circuits, poor insulation, and out-of-tolerance conditions in motor or transformer coils.
5. Withstand Voltage Test: Evaluate the withstand voltage leakage current between the stator winding and the shell. Features program-controlled voltage regulation, operable via computer.
6. No-load Test: Measure voltage, current, power, power factor, and frequency of the motor under no-load conditions (applicable to both single and three-phase motors).
7. Stall Rotor Test: Assess voltage, current, power, power factor, and frequency during motor stall rotor (instantaneous start) conditions (suitable for single and three-phase motors).
8. Power Supply: Operates on AC220V±15%, 50Hz±2 Hz, ensuring consistent system performance.
9. Operating Environment: Designed to function optimally in temperatures ranging from 0 to 40 °C.
10. Working Humidity: Operates efficiently in environments with humidity levels up to 70%.
11. Comprehensive Testing: All tests are completed with the first wiring setup.
12. Microcomputer Control: All testing processes are precisely managed by a microcomputer.
