Motor Stator Test System
The Motor Stator Test System harnesses the power of an industrial control computer for centralized and efficient management. With just one simple wiring setup, it seamlessly conducts all necessary tests. This includes critical national and enterprise mandatory inspection parameters such as power frequency withstand voltage, insulation resistance, inter-turn insulation, DC resistance, and rotor steering. This system stands out with its remarkable speed, unparalleled precision, user-friendly interface, and exceptional reliability. It automatically analyzes and evaluates the test results, and boasts comprehensive functionalities for statistical analysis, data storage, and report generation on a yearly, monthly, and daily basis. Moreover, it allows for presetting all parameters of the motor under test, making the testing process even more streamlined.
Key Features:
1. Test Items: DC resistance, insulation resistance, turn-to-turn test, withstand voltage test, motor steering test, inductance test
2. DC Resistance: Measures the resistance of the motor winding.
3. Insulation Resistance: Assesses the insulation resistance between the phase wire and the shell.
4. Inter-turn Test: Detects inter-turn and inter-layer short circuits, insulation failures, and out-of-tolerance conditions in motor or transformer coils.
5. Withstand Voltage Test: Evaluates the withstand voltage leakage current between the stator winding and the shell. Features programmable control and computer-regulated voltage adjustments.
6. Motor Steering: Determines the direction of the motor's magnetic field rotation.
7. Inductance Test: Measures the inductance of the motor coil.
8. Power Supply: Operates on AC220V±15%, 50Hz±2Hz.
9. Operating Environment: Designed to function optimally within a temperature range of 0~40°C.
10. Working Humidity: Efficiently performs under a humidity level of ≤70%.
11. All tests are seamlessly completed with a single clamping.
12. Entire testing process is governed by a microcomputer, ensuring precision and consistency.
