| Zusammenfassung: | The primary part (2) has a unit for production of a magnetic field and another unit for production of another magnetic field, where the units are arranged to realize superimposition of the former magnetic field with the latter magnetic field. A flux-guiding element is arranged on a side or both sides of the primary part to reduce a force ripple. The flux-guiding element is formed as an end tooth module (11) having a permanent magnet (12). The former unit is formed as single or polyphase winding, and the latter unit is formed as permanent magnet material. An independent claim is also included for a linear electrical machine comprising a primary part and a secondary part. |
