Special air-gap element for 2-D FEM analysis of electrical Machines accounting for rotor skew

The paper develops a special air-gap element based on the analytical solution of Laplace equation combined with standard finite elements, for analysis of electrical machines with rotor skew. It has been implemented for the analysis of a surface permanent-magnet machine. The results obtained have bee...

Description
Summary:The paper develops a special air-gap element based on the analytical solution of Laplace equation combined with standard finite elements, for analysis of electrical machines with rotor skew. It has been implemented for the analysis of a surface permanent-magnet machine. The results obtained have been compared to the ones of a standard 3-D finite-element model and are in good agreement with the measured ones.
