Advanced Motor Factory Online Test Bench
Our state-of-the-art online test bench at the motor factory utilizes an industrial control computer for centralized command, enabling the completion of all testing procedures through a single wiring setup. This system seamlessly integrates the measurement of various parameters, including power frequency withstand voltage, grounding resistance, motor speed, and no-load tests. It offers unparalleled advantages such as rapid test speeds, high precision, user-friendly operation, and exceptional reliability. Furthermore, it automatically analyzes and evaluates test outcomes. The system also features comprehensive functionalities for statistical analysis, data storage, and the generation of yearly, monthly, and daily reports. All motor parameters can be preset for precise testing.
Key Features:
