The invention relates to a linear motor and in particular a primary part of the linear motor for the movement of a secondary part, with a plurality of coils for inducing a magnetic field transmitting force along an axis between the primary part and the secondary part and with teeth, which are made from a magnetizable material, are arranged between adjacent coils and have a base section remote from the axis and an end section facing the axis, the teeth on the end section being wider than on the base section. In order to provide a primary part or a linear motor which also allow for high force densities given a compact design, the coils also extend in the interspace between the end sections of adjacent teeth so as to increase the magnetic flux density.

Primary part of a linear motor and linear motor therewith

An apparatus for reforming rod-shaped, electrically conductive and/or magnetizable materials, in particular for drawing and extruding, having the following features: the apparatus has a female mold having a die, which forms the tool for reforming; the apparatus has an inductor of an electric linear motor, by means of which a traveling electric field can be produced; the inductor includes at least one first group at least with first coils; the first coils in the first group are arranged axially next to one another and thus form a channel; using the inductor it is possible to produce a traveling field in the channel which has a magnetic flux density having a gradient in the axial direction of the channel, which has an amplitude of greater than B=1 T.
