Abstract

Methods of movement simulation in the coupled field-circuit analysis of rotating electric machines are considered. Special attention is paid to the application of moving band techniques in the finite element analysis of electromechanical transients. A new approach to the formulation of a band matrix as a function of rotor position is proposed. The matrix of the moving band is expressed by a trigonometric interpolating polynomial which is based on the matrices for discrete rotor positions. The method is verified by comparison of the analytical and numerical results of torque calculation and is applied in the analysis of permanent magnet motor dynamics
