The invention relates to a rotor (5), a stator (8) encompassing the rotor (5), at least one bearing bracket (9, 10) and a rotor cover (1). The electric motor is characteriezd in that the rotor cover (1) comprises at least one cover cap (2) extending from the bearing bracket (9) to at least the front face of the stator (8), which faces the bearing bracket (9). The invention also relates to a rotor cover for an inner rotor motor, comprising at least one cover cap (2) and cover fins (3) adjoining the cover cap (2), The cover cap (2) has a tapering portion from the side where the cover fins (3) are mounted, said cover fins (3) having a length corresponding to at least half of the length of the stator (8) of the electric motor (4).
