Motor Factory Online Test Bench
Our online test bench at the motor factory boasts cutting-edge industrial control computer technology for seamless centralized control. With just one wiring setup, it conducts a comprehensive range of tests, including power frequency withstand voltage, grounding resistance, motor speed, and no-load tests. This high-precision system offers rapid testing, user-friendly operation, and reliable performance. It automatically analyzes and judges test results, providing robust statistical reports that can be stored and printed daily, monthly, or yearly. All motor parameters can be preset for efficient testing.
Key Features:
1. Test Items: DC resistance, insulation resistance, inter-turn test, withstand voltage test, no-load test, stalled rotor test
2. DC Resistance: Accurately measure the motor winding resistance.
3. Insulation Resistance: Test the insulation resistance between the phase wire and the motor shell.
4. Inter-turn Test: Assess inter-turn short circuits, insulation issues, and coil out-of-tolerances in motors or transformers.
5. Withstand Voltage Test: Measure the leakage current in the withstand voltage test between the stator winding and the shell, with program-controlled voltage regulation that can be managed by a computer.
6. No-load Test: Evaluate the voltage, current, power, power factor, and frequency of the motor under no-load conditions (compatible with both single and three-phase).
7. Stalled Rotor Test: Measure the voltage, current, power, power factor, and frequency during the motor's stalled rotor state (motor instantaneous start), applicable to both single and three-phase setups.
8. Power Supply: AC220V±15%, 50Hz±2 Hz (suitable for system operation).
9. Operating Environment: Ensures optimal functionality within 0~40 °C temperature range.
10. Working Humidity: Operates efficiently under ≤70% humidity conditions.
11. Comprehensive Testing: All tests are executed from the initial wiring setup.
12. Microcomputer-Controlled Processes: Every testing process is managed by a microcomputer for precision and efficiency.
