Abstract [en]

In this paper, the influence of the welding processduring the manufacturing of small, slot-less permanent magnetsynchronous machines (PMSMs) is studied. The focus lies onthe change of the magnetic properties and the iron losses inthin, high quality Si-alloyed electrical steel sheets (NO 20). It isshown that the welding process changes the magnetic materialproperties significantly and increases the specific iron losses.Experimental results are provided for magnetic flux densitiesup to 1.3 T and frequencies in the range of 0.1Hz to 200Hz.
