Power electronics module with sealing jacket attached via an adhesion promoter; electric prime mover; as well as manufacturing processes

摘要

The invention relates to a power electronics module (1) for an electric drive machine (10) of a motor vehicle, with a plurality of busbars (2a, 2b, 2c) and a potting body (3) that supports the busbars (2a, 2b, 2c) at a distance and electrically insulated from one another, each busbar (2a, 2b, 2c) being exposed at a first connection area (4) and a second connection area (5) opposite the first connection area (4) for further contact to the surroundings of the potting body (3), the busbars ( 2a, 2b, 2c) each on a longitudinal section (8) arranged in a common recess (6) of the potting body (3) cast from a plastic material between its two connection areas (4, 5) with a separately applied to the potting body (3) Sealing casing (9) are provided, which sealing casing (9) adheres to the busbar (2a, 2b, 2c) via an adhesion promoter layer (7). The invention also relates to an electric drive machine (10) with this power electronics module (1) and a method of a power electronics module (1).
