Abstract

The invention relates to an electric motor comprising a housing (82) and a first bearing flange and a second bearing flange (10, 40). According to the invention, an edge (88, 90) of the housing is radially inwardly flanged over at least one of the bearing flanges (10, 40) along the periphery thereof.
