Abstract
Switched reluctance machine (SRM) has attracted more attention recently for its simple structure and high reliability. In this paper, an analytical method for solving the magnetic field in SRM is illustrated utilizing the Schwarz-Christoffel conformal mapping method. With the help of Matlab SC tools, a general radial flux SRM with linear material characteristic is analyzed. The flux density distribution along a contour in the airgap is obtained and torque is calculated using Maxwell stress tensor and compared with finite element method results. The comparisons show a good agreement and reveal the advantage of conformal mapping in time saving.
