Patent ID: 7154204

Claim:
A rotor for an electrical machine, comprising a short-circuit element ( 16 ) including a lamination packet ( 18 ) with a plurality of lamination elements ( 10 ), a number of permanent magnets disposed on the short-circuit element, at least one pair of fixation elements ( 14 ) on at least selected lamination elements ( 10 ), the fixation elements ( 14 ) being integral with the lamination elements ( 10 ); and a permanent magnet ( 22 ) being retained between two fixation elements ( 14 ) of one or more lamination elements ( 10 ) of the rotor, wherein the short-circuit element ( 16 ) comprises lamination elements ( 10 ) rotated relative to one another, between whose fixation elements ( 14 ) different permanent magnets ( 22 ) are retained, wherein the number of pairs of fixation elements on at least selected lamination elements ( 10 ) is lower than the number of permanent magnets disposed on the short-circuit element, and wherein the distance between each pair of fixation elements is essentially equal to the width of the permanent magnets.
