EFFECT OF STEEL LAMINATION ON CORE LOSSES IN SWITCHED RELUCTANCE MOTORS

The paper orients to investigate the influence of the steel lamination on the occurrence of the core losses in a three phase switched reluctance motor (SRM). The study attempts to compare the core losses in terms of its magnitude for the different types of core laminations on the motor with the same structure, operating under the same conditions. The effort involves the use of 2D finiteelement method (FEM) to obtain the core loss characteristics for a range of lamination thickness. The method allows a dynamic simulation procedure to evaluate the extent of loss reduction and suggest the choice of the appropriate size of the lamination for high speed applications.
