Abstract: In order to ensure the reliability, the fan needs to run in for a certain time before leaving the factory to screen out the products with abnormal operation. A fan running-in test platform based on LabVIEW was established, which can be used for three or even more fans in succession. The platform included on-off control system and data acquisition system. In the on-off control system, the programmable relay module was used to control the three-phase solid-state relay to realize the indirect control of the fan. In the data acquisition system, WT1600 power analyzer was used to collect the current and power of the fan during the test and transmit data to the computer. The overcurrent protection function was carried out by LabVIEW by combining with data acquisition system and on-off control system. The proposed running-in system not only improved efficiency, safety and reliability of the running in test platform, but also reduced the labor cost.
