The Static Testing System of Three-phase Linear Induction Motor Based on Virtual Instrument

Virtual Instrument (VI) is an outcome with the development of computer technique, modern measuring and testing technique, and electronic instrument technique. It is a new vivid kind of measuring instrument with well outlook. Compared to the testing system of conventional rotary motor, the one of three-phase linear induction motor (LIM) is quite different with the measuring of thrust and normal force. By virtual of the static testing system of 3-phase LIM developed by using PC as the CPU, based on PCI-6229 board, LabVIEW as the software developing platform, not only the structure of the system hardware have been simplified, but also the reliability of the system have been improved considerably so that the measuring precision and stability of all parameter could have been ensured.
