ABSTRACT:
In connection with a rotor for an electric motor, in particular a disk-type rotor comprising flat magnets being arranged in the form of angular segments and in spaced relationship and supported by supporting disks mounted on both sides of a central hub, it is proposed to provide the supporting disks with window-like openings corresponding to the contour of the said flat magnets so that the flat magnets are seated between the supporting disks without a cover in the axial direction and are secured by them against the effects of centrifugal forces in the sense of rotation and by an integrally formed outer marginal ring, the flat magnets being additionally guided and secured in the axial direction by inner projections formed integrally with the inner central annular disk area. The spoke-like webs which taper towards each other between the flat magnets form together with the outer integrally formed hoop-like ring a stiff triangular structure.
