Abstract
In order to simplify the adjustment of an axial play of a rotor shaft ( ) between the rotor shaft ( ) and a stator ( ) of a motor with the purpose of reducing the component expenditure and the assembly expenditure of the motor, respective clamp holders ( ) exert pressure on both sides of a plain bearing ( ). These clamp holders ( ) are axially moved to respective operating end positions in a bearing receiver ( ). There, the clamp holders ( ), which have different spring stiffniess, are fixed by respective claws. The clamp holder ( ) which has the higher spring stiffness adjusts the axial play of the rotor shaft ( ) while the clamp holder ( ) which has the lower spring stiffness exerts, in particular, an elastic axial pressure against the plain bearing ( ) and, therefore, against the first clamp holder ( ).
