This paper deals with the computation of the magnetic field and core losses in a squirrel-cage induction motor. The computational algorithm consists of the vector Preisach model incorporated in two-dimensional time-stepping finite element analysis. The hysteretic nonlinearity is handled by the fixed-point iterative technique. The comparison between the calculated and measured core losses for a 37 kW motor at no-load is given and indicates a reasonable agreement
