Abstract:
In a circuit module having components that are fastened to a substrate, the substrate includes a carrier layer made of metal and having a first surface, a first insulating layer bordering directly on the carrier layer being situated on the first surface. The substrate also includes a first wiring layer bordering directly on the first insulating layer, which conducts electrically and is situated on the first insulating layer. The substrate includes a first contact plane, which runs along the first surface, at least one of the components being directly connected electrically to the carrier layer in the first contact plane.
Abstract:
An electric motor (1) having a mount system (2) is used in particular as a motor for power-assisted steering. The mount system (2) has a roller bearing (8) in the form of a movable bearing, wherein a rolling-surface body (25; 26) of the roller bearing (8) has a groove in which a spring element (18) is arranged. When the electric motor (1) is mounted, the spring element (18) is prestressed in a radial direction (20), with the result that play-free mounting of a shaft (5) of the electric motor (1) is ensured in the radial direction (20) by means of the roller bearing (8).
Abstract:
The present invention relates to a stator assembly for an electrical machine, including a housing and a stator, in which the housing has at least one inward-oriented bead extending in the axial direction.
Abstract:
An electric motor has a stator and a coil which is arranged within the stator housing and whose winding can be energized via a connection line system. A cooling plate is arranged outside the interior of the stator, and on the outer side of said cooling plate a carrier plate for motor electronics is arranged, to which carrier plate the connection line system is connected. The connection line system is led from the inside to the outside through a recess in the cooling plate and is electrically connected to the carrier plate.
Abstract:
A drive device having an electric motor and an electronic control system for the electric motor, the electronic control system being disposed on a circuit carrier. Provision is made that the circuit carrier is a mechanical component, or part of a mechanical component, of the electric motor.
Abstract:
An electronic module includes a first substrate having at least one electronic component, and a housing embedded in the substrate and designed as an injection molded housing or a transfer molded housing, and which includes electrical leads protruding from the housing, connected to the first substrate and designed as a pressed screen. At least one further second substrate provided with second electrical is embedded in the housing, the second leads being designed as a second pressed screen, and the two pressed screens being directly connected to each other in at least one location.
