Introducing the cutting-edge Motor Factory Online Test Bench - designed for precision and efficiency.
The advanced online test bench from the motor factory employs an industrial control computer for seamless centralized control. This innovative system allows for the completion of all test items with just one wiring, encompassing a wide array of measurements such as power frequency withstand voltage, grounding resistance, motor speed, and no-load test. With unparalleled advantages like rapid test speed, high precision, user-friendly operation, and exceptional reliability, it also offers automatic analysis and judgment of test results. Additionally, it boasts comprehensive functions for statistics, storage, and printing of annual, monthly, and daily reports. All motor test parameters can be preset, ensuring streamlined testing processes.
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 with precision.
3. Insulation Resistance: Evaluates the insulation resistance between the phase wire and the casing.
4. Inter-Turn Test: Determines inter-turn and inter-layer short circuits, poor insulation, and tolerance issues in the motor or transformer coil.
5. Withstand Voltage Test: Assesses the withstand voltage leakage current between the stator winding and the casing, with programmable control and computer-regulated voltage settings.
6. No-Load Test: Measures voltage, current, power, power factor, and frequency of the motor under no-load conditions (suitable for both single and three-phase motors).
7. Stall Rotor Test: Evaluates voltage, current, power, power factor, and frequency during motor stall conditions (instantaneous start) for both single and three-phase motors.
8. Power Supply: AC220V±15%, 50Hz±2 Hz (system working power supply).
9. Operating Environment: Optimized for a working temperature of 0~40 °C.
10. Working Humidity: Maintains efficiency at humidity levels ≤70%.
11. Completion of all tests with a single wiring setup.
12. Microcomputer-controlled testing processes for absolute precision.
