Abstract: An electronically commutated DC motor has a stator wound with a multi-phase stator winding, a permanent magnet rotor mounted rotatably about a motor axis, a circuit board, a guide plate electrically connected to the winding and a housing component. In one implementation, a DC motor can easily be manufactured with the fewest possible process steps, which exhibits a short axial length and a low weight as well as good heat-dissipation properties. It is also an object of the invention to create a DC motor with integrated electronics, whose motor interior can be filled with oil, and which holds the electronics sealed against this oil. For reasons of logistics, an attempt is also made for partial components, such as the electronics, to be designed such that they are capable of complete prior assembly and testing.

Abstract: A device for detecting the angle of rotation of a throttle valve operated by an electric motor is disclosed. The valve is rotatably supported on a throttle valve shaft in an intake system of a throttle valve housing, wherein an actuator motor coupled to the throttle valve shaft predefines the throttle valve angular position in a manner controlled by a control unit, and wherein a predetermined value of the throttle valve angular position is predetermined by a manually operated predetermined-value input apparatus and is fed to the control unit. The predetermined-value input apparatus is coupled to a predetermined value sensor shaft, wherein the angular position of the predetermined value sensor shaft corresponds to the manually predefined predetermined value of the throttle valve angular position.
