Abstract

In the analysis of switched reluctance motors (SRMs), the analytical error of 2D FEA caused by the magnetic flux change in the direction of the axis, which is not considered in 2D FEA, is a serious problem. In this paper, a novel method for making a 2D-FEA model of an SRM, which can equivalently consider the influence of the threedimensional effect, is proposed. A 2D-FEA model of an SRM can be easily made by adjusting only the shape of two regions in a rotor by employing the proposed method. The optimum values of two parameters, defined in this paper for adjusting the shapes of the rotor with the proposed method, are easily extrapolated. A comparison of the experimental results with 2D FEA using the proposed method confirms that the proposed method is effective in considering the three-dimensional effect.
