Abstract

In this paper, an analytical model to calculate a canned switched reluctance machine (SRM) is presented. Such a model is characterized by a multilayer structure in a cylindrical coordinate. Maxwell´s equations are used to derive the magnetomotive force (MMF) distribution of the stator armature and determine the arrangement of wires within a coil. The large rotor and stator slots of double saliency are taken using the magnetic equivalent circuit (MEC) method with adjustable elements. Based on Poynting´s theorem, the loss from each part of the machine is obtained, including the can loss and iron loss. Finally, torque is deduced by a Maxwell stress tensor.
