Two-dimension Electromagnetic Field Software Platform Of Permanent Magnetic Electrical Machines

According to the development of the 2-D electromagnetic field software platform of PM electrical machines electromagnetic field computation, this dissertation is devoted to do research on modeling, electromagnetic field revolving computation, module of scheduler, and the graphics technology of electromagnetic field. Four parts are included as follows:First of all, a model base and a universal method of modelling for PM electrical machines electromagnetic field are given. The workload for PM electrical machines electromagnetic field is reduced so much.The electromagnetic field computation region is expanded and all region electromagnetic field computation of electrical machine is realized. The electromagnetic field of electrical machine at different position of rotor is analyzed. The real-time computation for electrical machine electromagnetic field revolving is finished. The interface for Visual Basic and Fortran is programmed. The data transfer is completed among programs. The dissertation establishes the reasonable program structure combined with advanced computer technology such as multi-thread in order to shorten computation time. At the same time, the module of scheduler is established and some programs are unproved by the ways of dynamic link library.The display is strengthened by graphics technology; and the interface between Visual Basic and Access is solved. The memory of data result is finished dynamically. The Data Base Management System (DBMS) is built.The software is validated by analytical method and ANSYS. The application of developed software to the treatment of electromagnetic field computation results of permanent magnetic electrical machine indicates that the graphic can provide designers valuable figurative reference.
