The invention is characterized in that an intermediate element is coordinated with a plurality of magnet arrays. The intermediate element is in a radial direction arranged between the inner and the outer magnet and extends beyond their axial length. The intermediate element is suited for insertion in mating grooves in the rings end ring, spacer ring and central support disk--adjoining the separate rows, of in peripheral direction having alternately magnetized magnet arrays with interposed collector or soft-iron elements.

[ What is claimed is:] [1.] A rotor for an electric machine, said rotor comprising:at least one support disk having an end face;at least one annular pole structure arranged on said end face, said annular pole structure coaxial to the rotor axis and extending in axial direction;a spacer ring of magnetically and electrically nonconducting material;said pole structure having two adjacent, in peripheral direction, alternately magnetized magnet arrays with interposed collector elements, said rows separated by said spacer ring magnetic arrays include an inner and an outer magnet;an end ring coordinated with each said pole structure; said end ring, said spacer ring and said support disk having mating grooves adjoining the separate row in peripheral direction of said alternately magnetized magnet arrays with interposed collector elements, said collector elements adjoining said magnet array in peripheral direction designed so that they form a first inside stop and a second outside stop for said magnet array in the radial direction;protruding elements coordinated with said rows, in a peripheral direction, to said alternately magnetized magnet arrays with interposed collector elements said protruding elements in axial direction protrude on both sides of said array, said protruding elements suited for insertion into said mating grooves;an intermediate element having said protruding elements located on opposite ends, said intermediate elements composed of nonmagnetic material; andsaid protruding elements are in radial direction disposed between said inner and said outer magnet and extend in an axial direction beyond said inner and said outer magnet lengths.
