Abstract:
1. Electric motor ( 10 ) for adjusting moving parts in a motor vehicle, comprising an electronic unit ( 70 ) with a sandwich construction, which contains a first electrically conductive substrate ( 71 ) and a second electric conductive substrate ( 72 ), between which power components ( 75 ) are located and electrically connected to both substrates ( 71 , 72 ), and a side ( 84 ) of the second substrate ( 72 ) facing away from the first substrate ( 71 ) is equipped with additional electronic components ( 56 ), wherein the first substrate ( 71 ) is a punched grid ( 44 ) punched from a metal material, the punched grid ( 44 ) being directly electrically and mechanically connected to the power components ( 75 ), the punched grid ( 44 ) supporting the power components ( 75 ), the punched grid ( 44 ) together with the second substrate ( 72 ) is extrusion coated with and totally encapsulated by a plastic body ( 95 ) produced by injection molding in such a way that only extensions ( 97 ) of the punched grid ( 44 ) protrude from the plastic body ( 95 ), forming an electrical and/or mechanical interface ( 98 ) for connecting additional motor components ( 99 , 38 , 40 , 104 , 102 , 80 ).
