Disclosed is an electric motor (20) comprising a stator (30) and a rotor (26) which has a cup-type rotor part (56) and a magnet ring (60). Said magnet ring (60) is glued to the rotor part (56) and has an external circumference (61) on which elevations (84) and depressions (86) are provided that extend at least in part in the longitudinal direction of the magnet ring (60). The external circumference (61) of the magnet ring (60) faces the cup-type rotor part (56) after assembly and has at least one recess (68; 88) which extends in the circumferential direction and is connected to at least part of the shallow depression (86).
