摘要

The system (1) has an electric servomotor (7) accommodated in a bearing housing (8) that is provided with a mounting platform for retaining a power electronics unit. The servomotor is coupled with a steering shaft (3). The power electronics unit is adjustably arranged in an electronic housing that is connected to the bearing housing. The power electronics unit is adjustable between a mounting position, in which the electronics unit is spaced from the platform, and an operative position, in which the electronics unit lies on the platform. A heat conductive medium is applied on the platform.
