Abstract: The two bearing brackets (4, 5) of a small motor are clamped by means of stud screws (2, 3) against the respective end face of the motor casing (1). The stud screws (2, 3) extend axially by free bolt ends (21, 31) beyond one bearing bracket (5). Onto these free bolt ends (21, 31), a holding frame for the small motor is placed and is fixed against the bearing bracket (5) by means of a holding nut to be screwed onto the free bolt ends (21, 31). The screw heads (22, 23) provided at the stud screw ends are held positively in the one bearing bracket (4) to prevent their rotation with respect to the casing and onto the other, axially projecting free bolt end (21, 31) an attachment nut (23, 33) is screwed applying firmly against the other bearing bracket (5).

Abstract: The object of the invention is to provide a means of limiting the axial play of a motor shaft while dispensing with the use of an adjustable stop screw that has to be secured separately after it has been set. In particular, and apparatus is provided that can be used with automated manipulators. For this purpose it is recommended, according to the invention, that as a stopping element a single piece disk of appropriate thickness or a single piece disk stamped parallel to the motor assembly machine out of strip material, with an axially stamped depression of appropriate depth, is to be inserted rigidly in a pocket fixed in the housing. The invention is particularly well-suited for application in small motors with a shaft mounted on plain bearings.
