Abstract:
Rotor for an electric machine, especially a transversal flow machinewith at least one pole structure,the pole structure comprises two adjacent rows of magnet arrangements alternately magnetized in the peripheral direction with collector and soft iron elements lying in between, separated by an intermediate layer of magnetically and electrically nonconducting material;the magnet arrangements are connected in shape-mated fashion in the peripheral direction to the adjacent collector and soft iron elements;the collector and soft iron elements are at least partially provided with an insulation layer;each collector and soft iron element includes a radial extension which extends radially beyond a radial end surface of each of the magnet arrangements;at least one of collector and soft iron elements adjacent to a magnet arrangement in the peripheral direction includes a radially outward stop surface for at least indirect support of the magnet arrangement in the radial direction;and wherein at least one of the collector and soft iron elements adjacent to the magnet arrangement in the peripheral direction is free of a radially outward stop surface for at least indirect support of the magnet arrangement in the radial direction.
