Abstract

An electric motor 1 consisting of a stator 4 comprising a housing 3, a rotor 5 which comprises a shaft 6 mounted in such a manner that it can rotate in the stator 4, and a sealing element 2 which seals a rotor space 7 enclosed by a housing 3 from an additional space 8 contaminated with harmful materials. The sealing element 2 consists of an elastic sealing plate 9 of at least approximately constant thickness, said elastic sealing plate comprising a central recess 10 which receives a section of the shaft 6 and an annular surface area 11 in contact with the housing 3, and an arrester plate 12 which is pressed firmly onto the shaft 6 and causes the contact of the sealing plate 9 with the housing 3, and that the distance between one side of the arrester plate 12, specifically the front side facing the housing 3, and the housing area 15 in contact with the sealing plate 9 is less than the thickness of the sealing plate 9.
