Abstract
A primary part of a linear electrical machine includes a first member for production of a first magnetic field, a second member for production of a second magnetic field. The first member and the second member are arranged to realize a superimposition of the first magnetic field with the second magnetic field. Arranged on at least one end face of the primary part is a flux-guiding element to reduce a force ripple. The flux-guiding element is constructed in the form of an end tooth module having at least one permanent magnet.
