Study on circle-annulus meshing methods using ANSYS software and its application in motor electromagnetic field analysis

Air-gap circle-annulus meshing plays an important role for analytical accuracy and precision in motor electromagnetic field analysis. Three meshing methods are correspondingly presented based on three distributions of stator and rotor located in the air-gap circle-annulus. The end of the paper goes on a simulation example and gets an accuracy simulation result of a motor electromagnetic field analysis, and the simulation results indicate that the air-gap circle-annulus meshing methods are effective and correct.
