Magnetic flux conducting arrangement for use as e.g. rotor arrangement of electric machine, has identical lamella sheets arranged on top of each other in direction of arrangement for forming area with increased magnetic resistance

摘要

The arrangement has a set of identical lamella sheets (4) made of magnetic material i.e. ferrite material, where the sheets have a reduced thickness in an area (5). The sheets are arranged on top of each other in a direction of the arrangement for forming the area with increased magnetic resistance and for forming magnetic fluxes in the direction transverse to the arrangement direction. The sheets are displaced transverse to the arrangement direction and are pivotable around the arrangement direction, such that the sheets are arranged in different displaced and/or pivoted positions. An independent claim is also included for a method for manufacturing lamella sheets for a magnetic flux conducting arrangement.
