Abstract
AbstractMajor components of electrical motors are toroidal cores made of stacked electrical steel sheets. All common joining methods cause a degradation of the magnetic properties of the toroidal cores. In this paper, pulsed laser beam welding in vacuum is used to join the individual electrical steel sheets. It is shown that the magnetic behaviour of the toroidal cores can be influenced by variation of process parameters like beam power and working pressure.
