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.
