Simplified Calculation of Open Domain of Magnetic Field in Engineering
Mass electromagnetism phenomena occur in open domain. But because of the difficulty of calculation, open domain problems are often simplified as equivalent model in the finite space in order to save time of modeling and analyzing in the computer. Taking a disk coreless permanent magnet synchronous motor (PMSM) as an example, the FEM analysis is done to simplify open domain of magnetic field. Aiming at a difficult problem of the modeling and solving to the open domain of magnetic field, it is very important to reduce fact domain effectively. The FEM analysis has been done to prove that the method reducing the open domain into the smallest domain could obtain approximately the accurate results, at the same time the EMS memory and the time are reduced obviously. So the intention of simplification is achieved.
