Electrical equipment for use in active steering system of motor vehicle, has folded board comprising shield segments, power segments and small-signal segments aligned different from each other, and shielding layer formed in bending zones

摘要

The equipment has a folded board (1) forming a four-sided shielded housing. The folded board has shield segments (2), power segments (6) and small-signal segments that are aligned different from each other and non-parallel to each other. The segments are connected with each other by bending zones. The folded board has a shielding layer that is formed in the bending zones. A power electronics unit (11) controls an electric motor (10) and is arranged on the shield and power segments of the folded board.
