Abstract

In an electric motor having a rotor which is arranged in a rotationally fixed manner on a shaft (4), a fixed bearing (7) is prestressed axially against a stop (9) by a spring element (11) in order to bear the shaft (4). The spring element (11) has an annular shape and has a larger external diameter than the fixed bearing (7). A rim (13), which is produced by peening, of the bearing plate (5) engages behind the external circumference of the element (11).
