Abstract
An electric motor has a rotor, a stator encompassing the rotor, at least one bearing bracket, and a rotor cover. The rotor cover has at least one cover cap extending from the bearing bracket to at least the front face of the stator, which faces the bearing bracket. The invention also relates to a rotor cover for an inner rotor motor, having at least one cover cap and cover fins adjoining the cover cap. The cover cap has a tapering portion from the side where the cover fins are mounted. The cover fins have a length corresponding to at least half of the length of the stator of the electric motor.
