Introducing our state-of-the-art Motor Test Bench, designed for seamless online factory testing.
Our advanced online test bench for motor factories is managed through a robust industrial control computer, allowing for centralized control. This system integrates multiple essential measurements-including power frequency withstand voltage, grounding resistance, motor speed, and no-load tests-into one streamlined process with a single wiring setup. Not only does it ensure rapid testing with high precision, but it is also user-friendly and highly reliable. The system automatically analyzes and judges test results, while also offering comprehensive statistical functions with options to store and print yearly, monthly, and daily reports. All motor parameters can be preset for efficient testing.
Key Features:
1. Comprehensive Test Items: Includes DC resistance, insulation resistance, turn-to-turn tests, withstand voltage tests, no-load tests, and blocked rotor tests.
2. DC Resistance Measurement: Accurately tests the resistance of motor windings.
3. Insulation Resistance Measurement: Evaluates the insulation resistance between phase wires and the motor shell.
4. Turn-to-Turn Testing: Diagnoses inter-turn and inter-layer short circuits, poor insulation, and coil tolerance issues within motors or transformers.
5. Withstand Voltage Testing: Measures leakage current between stator windings and the shell, with programmable and computer-controlled voltage regulation.
6. No-Load Testing: Measures voltage, current, power, power factor, and frequency for motors operating without load (applicable to both single and three-phase).
7. Stall Rotor Testing: Evaluates voltage, current, power, power factor, and frequency during motor stall (instantaneous start) conditions (applicable to both single and three-phase).
8. Power Supply Specifications: Operates on AC220V±15%, 50Hz±2Hz for reliable system performance.
9. Operating Environment: Ideal working temperature ranges from 0 to 40 °C.
10. Humidity Specifications: Operates efficiently with working humidity levels ≤70%.
11. Single Wiring Completion: All tests are completed with the first wiring setup.
12. Automated Testing: All testing processes are meticulously controlled by a microcomputer.
