Electric motor

An electric motor including a tubular housing member (1) and at least one cover (2) secured thereto, said cover (2) having an insertion area (3) at a front side (10) of the cover, which is inserted in said housing member (1) in an essentially tight-fitting manner and which is connected to said housing member (1) by means of at least one deformable portion (8) of an end face area (6) of said housing member (1), said cover (2) abutting an end face (5) of said housing member (1) via a flange (4), said cover having at least one cavity (7) in a transition region between said insertion area (3) and said flange (4), each of said at least one cavity (7) being accessible from outside the motor via an access opening (7') in a rear side of said cover (2) and terminating at an undercut portion (9) of said insertion area (3), and wherein each of said cavities has an axis which is parallel to the axis of the motor, each of said cavities expose a portion of the insertion area (3) and expose said deformable portion (8) of the end face area (6) of the housing member (1), each of said deformable portions (8) of said end face area (6) of said housing member (1) being deformed into engagement with said undercut portion (9) by means of moving a ram (11) into said access opening, whereby said cover (2) is locked in position on said housing member (1) and said deformable portions of the end face area (6) of the housing member (1) are located at protected points within an area substantially enclosed by the outer circumference of the housing member (1) and the flange (4) of the cover (2).
