摘要： Described is an electrical machine (1) which comprises two end shields (6, 7), a stator (5) which is arranged between the two end shields (6, 7) and has a stator laminated core (11, 11a) and stator windings (12) arranged therein, and a rotor (3) which is arranged in the stator (5) and has a rotor shaft (2) mounted rotatably in the two end shields (6, 7). The electrical machine (1) furthermore has cooling channels (13) arranged fully in the stator laminated core (11, 11a) and edged by the latter. Furthermore described are a gear motor (30) comprising such an electrical machine (1), as well as a vehicle (20) comprising such an electrical machine (1).

摘要： 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.
