The paper deals with a proposed coupled FE-BE method based on the coupling of the finite element and boundary element methods to compute parameters such as flux linkage, inductance and static torque of an 8/6 switched reluctance motor (SRM). The combination of both techniques in the same computer program is the most efficient way of tackling problems that contain features requiring both FE and BE capabilities. The conducting and magnetic parts of the motor are discritized by the finite element whereas the boundary element is used to discritize its air gap. The interfaces between the two methods’ domains were chosen to be circular to avoid the discontinuity of the normal vector at the corners of poles. To illustrate the merits of such proposed coupled FE-BE method, the obtained simulation results are compared to the prototype design values of this motor as cited in a given reference.
