MAGNETIC-FIELD AND CORE LOSS EVALUATION OF ALA-ROTOR SYNCHRONOUS RELUCTANCE MACHINES TAKING INTO ACCOUNT MATERIAL ANISOTROPY

Currently, much attention is paid to the behavior of thin laminations of anisotropic soft magnetic materials with respect to magnetization o ut of the easy axis. A method for analyzing flux distribution and loss calculation is proposed for electric machines exhibiting strong mater ial and 'structural' anisotropy, The method takes into account the cur vature in anisotropic and composite flux barrier regions by introducin g equivalent reluctivities. The results of a case study on an axially laminated anisotropic (ALA) rotor of a synchronous reluctance motor (S ynRM) are presented.
