ABSTRACT:
The aim of the invention is to better adapt the power range of a linear motor to specific applications. For this purpose, the secondary part (2) is subdivided into at least one first (3) and one second section (4) in the direction of travel (15) of the primary part (1). The secondary part (2), in the first section (3), has a different shape than in the second section (4) and/or is produced from a different material. In this manner, different speeds of the primary part (1) can be achieved on the traveled distance independent of the actuation of the primary part. Optionally, cage windings can be inserted in a section of the secondary part so that said secondary part can be used for passive breaking.
