Abstract

A transversal flux machine having a stator arrangement with a stator housing and at least one pole system arranged inside the stator housing and extending in the rotating direction. The pole system has an essentially U-shaped cross-section, and a ring winding received in the recess between the legs of the U-shaped cross-section and extending in the rotating direction, as well as having at least one rotor arrangement with at least one row of alternatingly arranged permanent magnets and soft-iron reflux elements. On the stator side, one retaining ring is provided on the rotor side of each ring winding respectively. The retaining ring has on both edge areas equidistantly spaced recesses for receiving radially inwardly projecting teeth of the pole rings and is used for stabilizing the pole system and the ring coil. On the rotor side, each row of alternatingly arranged permanent magnets and soft-iron reflux magnets extending in the rotating direction is held by a rotor support which has on each side an outer fastening ring with a projection extending at its radially outer end axially toward the inside, against which projection the permanent magnets and the soft-iron reflux elements are …
