摘要: Axial mechanical stress on electrical steel significantly affects the magnetic properties of electric steel. The magnetizability is reduced and losses are increased. In machines, axial induced in different processes production. lamination stacks often compressed by means pressure to create a compact robust core. This work focuses influence rotor stack from new low cost assembly. A setup constructed measure ring core samples made Extensive measurements at values conducted. From measured data, an iron loss model parametrized. hysteresis eddy current discussed. identified parameters applied solution 2D FEM simulation permanent magnet synchronous machine. characteristics machine studied.
