KEYWORDSOptimization; Surface current method; Electric magnet and nite element method.Abstract. In this paper, application of the Surface Current Method (SCM) in analysis and optimization of electromechanical devices is proposed. SCM is one of the numerical techniques in electromagnetic eld analysis. In SCM, only magnetic boundaries are subdivided against Finite Element Method (FEM) which is subdivided into all of domains; therefore, the calculation resources of SCM are much lower than FEM. SCM with low-calculation resource is one of the best numerical techniques for magnetic devices' optimization. In this paper, using SCM, three electromechanical systems have been optimized based on minimization of weight per force. Veri cation of simulation results is done by FEM.

“…A new nonlinear analysis (saturation effect is considered) using combination of the Finite difference and the SCM named FDSCM (Finite Difference Surface Current Method) is presented in [8]. An analysis of rotating single phase reluctance motor with constant speed using the SCM is done and compared with the FEM [9]. Coupling between electric and magnetic circuit using the SCM was developed on a linear dynamic analysis (no saturation) in the electrometrical system (relay configuration) without any moving object [10].…”

In this paper, a new sampling point refinement for saturation modeling in Surface Current Method (SCM) is proposed. In this method the variable permeability inside the magnetic materials due to the saturation is defined by optimization of sampling point number and their positions. In other words, the sampling points inside the material are refined for any current value and air gap variation. These results depend on magnetic energy of sampling points inside the material and the value of them is strongly depend on sampling point positions. Simulation results verification have been done with the FEM.

In this paper a new method for coupling each subdivision the linear system in it unknowns J is between electric and magnetic circuit using Surface Current e Method (SCM) is proposed. In this method inductance of coils obtained [4]: is calculated via SCM. SCM simulation results with 416 meshes are compared with Analytical and Finite Element Method with [M][J"] -[Bs](1) 1600 meshes that they are very close together.
