2D Analytical Subdomain Model of Surface-Mounted PM Machines Accounting for Step-skewed Magnets
The subdomain model for analytical calculation of magnetic field is widely developed to predict electromagnetic performance in permanent magnet (PM) machines. Based on the principle of the mutual flux through the stator windings due to step-skewed PMs identical to that from equivalent non-skewed (PM), a 2D subdomain model of surface-mounted PM machines accounting for step-skewed magnets is proposed. By resolving the analytical expressions of the equivalent PMs subdomain, the 3D problem of step-skewed magnets along axis is simplified to a 2D problem, which saves the computational resources and improves the efficiency. The 2D multislice finite-element analysis confirms accuracy of the analytical method.
