Apparatus for shaping of bar-shaped or tubular electrically conductive or magnetisable workpieces

摘要

The arrangement has an inductor (1) for an electric motor with which a traveling electromagnetic field can be generated and that contains axially adjacent coils (3) that form a channel and one or more arrangements (4,5) for conducting magnetic flux that are removably arranged in the channel. A first flux conducting arrangement is in the form of a pipe (4) with a first section (4a) of magnetisable material and a second section (4b) of non-magnetisable or only weakly magnetisable material.
