High Accuracy Torque Calculation for a Rotating Machine Using Adaptive Meshing

摘要

A new two dimensional adaptive meshing method for the analysis of rotating machines is presented. The method takes model symmetries and the force distribution into account when refining the mesh. This allows for a more accurate determination of the cogging torque than using a standard adaptive scheme. A flat-type permanent magnet motor has been modeled to show the effectiveness of the method.
