AC iron loss investigation with consideration of a DC bias magnetisation in non-grain oriented electrical steel sheets

Description

This work deals with the characterisation of AC iron losses, of non grain oriented (NO) soft magnetic steel sheets, under the presence of a DC bias magnetisation. Such DC fields occur in multiple electrical motor topologies, e.g., permanent magnet synchronous machines (PMSM), and lead to increased local iron losses, and therefore a greater demagnetisation risk of permanent magnets in use. Hence, this loss increase needs to be accounted for. Furthermore, due to the DC bias, the permeability of the material is decreasing. Three different NO material grades in six different ring geometries are subject to this metrological investigation
