Intelligent Voltage Adjustment System for Motor Testing Based on LabVIEW

The intelligent voltage adjustment system is the key part of intelligent and digital motor testing system, and its object is to provide the main circuit power for the tested motor safely and effectively. The system based on virtual instrument technology adjusts the rotate speed of asynchronous motor in transformer through sending command to transducer, and then controls the output voltage of transformer. The experimental results show that the voltage adjustment process of the system has good smoothness, robustness and real-time with high practical application value.
