Storage system for an electric motor

An electric motor (1) with a bearing system (2) is used in particular as a motor for a power steering. The storage system (2) has a floating bearing formed as a roller bearing (8), wherein a race body (25; 26) of the bearing (8) has a groove in which a spring element (18) is arranged. When mounting of the electric motor (1), the spring element (18) in a radial direction (20) is biased so that a play-free mounting of a shaft (5) of the electric motor (1) through the roller bearing (8) in the radial direction (20) is guaranteed.
