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.
