An electrical machine, in particular an electronically commutated machine, includes a housing and a controller accommodated in the housing. The controller is configured to drive the machine to generate a magnetic rotating field. The housing has a housing cup, which surrounds a hollow space, and a housing cover. The machine has an end plate accommodated in the housing cup. The end plate is thermally conductively connected to the housing cup. The machine also has a cooling panel thermally conductively connected to the housing cup and to at least one component, or to a plurality of components, of the control unit. The machine has an inverter comprising semiconductor switches. The semiconductor switches are thermally conductively connected to the end plate. The end plate and the cooling panel enclose a portion of the hollow space.

An electromechanical actuator for rack-and-pinion steering includes a stator, rotor, and electronic system. The electronic system includes at least one first electronic sub-system and a second electronic subsystem, each operatively connected to the stator and the rotor. The at least one first electronic sub-system is arranged at least on a first circuit carrier plane and a second circuit carrier plane, and includes a first power output stage, a first control unit, and a first rotor position sensor arrangement. The second electronic sub-system is arranged at least on the first circuit carrier plane and a third circuit carrier plane, and includes a second power output stage, a second control unit, and a second rotor position sensor arrangement. The first, second and third circuit carrier planes are arranged perpendicular to an axis of rotation of the rotor, and are spaced apart from each other along the axis of rotation.

A circuit arrangement for de-exciting an excitation winding of a synchronous machine in the event of a fault, including a control circuit for controlling a current flow through the excitation winding, it being possible to apply a positive control voltage to the excitation winding for excitation and a negative control voltage for rapid de-excitation, and including a protective circuit which is parallel-connected to the excitation winding and which does not permit a current flow over the protective circuit in the event of rapid de-excitation and which forms a current path for limiting the voltage and de-exciting the excitation winding if at least one connecting line between the control circuit and the excitation winding is interrupted.

In a system for the electrical contacting of at least one connection element of an electronic circuit in a hermetically sealed housing with a conductor element having a base plate for holding the at least one connection element, the conductor element is provided with a press-in pin which may be pressed-in in one section of the connection element to form a contact.
