Abstract
A brush assembly (2) with a plug housing (3) is inserted into an axial opening of a motor housing (1) so that interference suppression devices (5, 6) can be connected easily from a production point of view and the plug terminals and the brush apparatus can be protected against corrosive media. The plug housing is formed with pockets which hold the interference suppression devices and the plug terminals for easy assembly.
