Module for controllers and brush holders and method of manfacturing it

A module for an electronic circuit of chip or hybrid design, combined with a brush holder for electrical machines, comprising a housing component consisting of insulating material and having a collar with an opening;

• a brush holder with carbon brushes;
• a controller circuit for said carbon brushes and having a contact component embedded in said housing component with the exception of contact areas of said contact component which are free of the insulating material of said housing component while all remaining areas of said contact component are embedded in the insulating material of said housing component;
• an electrically conductive bearing plate, said controller circuit being fixed as a controller circuit on said bearing plate at ground potential and surrounded by said collar of said housing component, said housing component being attached to said bearing plate and being connected to said contact areas, said contact areas projecting into said opening of said collar;
• a lid closing said opening of said collar;
• and attachment means for attaching said bearing plate to said housing component in order to dissipate heat, said brush holder together with its contact components for terminals of said carbon brushes being formed of one piece with said housing component composed of insulating material, said controller circuit with said collar surrounding it being arranged on a front side of said bearing plate in a central area of the brush holder and next to them on one half of said bearing plate, another half of said bearing plate remaining essentially free in order to dissipate heat to cooling air.
