The basic configuration, software and hardware design methods of fan high efficiency operation control system were introduced. High efficiency operation control model of the fan was built, and speed control methods of the fan were selected. Fan control system based on frequency converter and LabVIEW was built. This system was mainly composed of frequency converter system and data acquisition and condition monitoring system. The system had the following advantages: highefficiency, energysaving, reliable performance. The development of the system is very importance to safety performance and energysaving and costreducing of fans.
