Abstract: A rotor of an electrical machine comprising pole pieces representing laminated packs of flux-conducting lamellae, and permanent magnets directly contacting the pole terminals, gaps being provided between the flux-conducting lamellae. The gaps are provided by projections on the lamellae themselves. The magnetic flux created by the permanent magnets is conducted through the pole pieces which are usually magnetically unsaturated. Since the latter consists of flux-conducting lamellae between which gaps are provided, the weight and inertia moment of the rotor are reduced without reducing the magnitude of the magnetic flux in the machine.

Abstract: A rotor for an electrical machine with tangentially oriented permanent magnets between which pole pieces are arranged, the rotor featuring radial axes of the arcs of the pole pieces arranged between the radial axes of the pole piece cores and the radial axes of the magnets, the above arcs partially and unilaterally overlapping the magnets. The longitudinal axes of the pole piece arcs alternate in position to form a broken line while the longitudinal axes of the pole piece cores and of the magnets are aligned to form continuous lines. This reduces the magnetic dissipation flux and the unevenness of rotation of the machine.
