Virtual experimental system for parameter determination of three-phase asynchronous motor

For the high cost of electrical motor tests, the virtual experimental system for parameter determination of three-phase asynchronous motor was designed with Visual C ＋ ＋. The mathematical models of no-load test and blocked-rotor test were established, and the experimental process was realized by virtual simulation technology. By combination of software programming, the functions of data processing, analysis and curve drawing were achieved. The concept of virtual instruments was applied to the traditional electrical experiments, which effectively supported electrical motor teaching activities. With flexible virtual laboratory, students have more opportunities for practice, they are more interested in experiment and thus can further understand the theoretical knowledge, and more important, students are encouraged to investigate in depth.
