Abstract: A rotor for an electric machine includes a sheet metal package formed from stacked electrical sheets and having magnet pockets arranged therein, a plurality of magnets of which at least one is inserted into each of the magnet pockets, a plurality of clearances which are each delimited by the magnets inserted into one of the magnet pockets and by the sheet metal package, a filling opening which is arranged on an axial side of the sheet metal package and through which a first of the clearances is exposed, and a venting opening which is arranged on the axial side and through which a second of the clearances is exposed. The outer end of the filling opening and/or the outer end of the venting opening are widened. Also described are an electric machine having the rotor, a vehicle having the machine and a method for producing the rotor.
