Introducing the ultimate motor factory online test bench: A cutting-edge solution for comprehensive motor testing.
Our state-of-the-art online test bench at the motor factory leverages advanced industrial control computers for centralized management. This innovative system completes all testing tasks through a single wiring setup, seamlessly integrating multiple measurements such as power frequency withstand voltage, grounding resistance, motor speed, and no-load tests. Enjoy unparalleled benefits like rapid testing speed, exceptional accuracy, user-friendly operation, and robust reliability. It automatically analyzes and evaluates test results, while also offering functions for statistics, storage, and printing of yearly, monthly, and daily reports. All parameters of the motor under test can be preset, ensuring a streamlined and efficient testing process.
Key Features:
1. Comprehensive Test Items: DC resistance, insulation resistance, turn-to-turn test, withstand voltage test, no-load test, blocked rotor test
2. DC Resistance: Accurately measure the resistance of motor winding resistance
3. Insulation Resistance: Evaluate the insulation resistance between phase wires and the shell
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: Measure the withstand voltage leakage current between the stator winding and the shell. Program control and computer-controlled voltage regulation ensure precision.
6. No-Load Test: Assess the 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: Measure the voltage, current, power, power factor, and frequency during motor stall rotor conditions (motor instantaneous start) for both single and three-phase motors
8. Power Supply: Compatible with AC220V±15%, 50Hz±2Hz system working power supply
9. Operating Environment: Optimal working temperature range of 0~40°C
10. Humidity Tolerance: Working humidity should be ≤70%
11. Complete all tests with just one wiring setup.
12. All testing procedures are fully controlled by an advanced microcomputer system.
