Magnetic Field Analysis of Surface-Mounted Permanent-Magnet Synchronous Motors Using Analytical and Numerical Conformal Mapping
In this paper we apply analytical and numerical conformal mapping (CM) to analyze magnetic field originating from permanent magnets and armature winding currents in a slotted air-gap of a surface mounted radial permanent-magnet synchronous motor (SPM) with taking into account the effect of arbitrarily curved motor surfaces. One of the conformal mappings used in this study, which is the numerical solution of the Schwarz-Christoffel (SC) integral, is obtained using Matlab SC Toolbox. We used this field solution to calculate cogging torque and electromagnetic torque by integrating the Maxwell stress tensor inside the air-gap. The accuracy of the developed method is verified by comparing its results with those obtained from the developed numerical finite-element (FE) model.
