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.

A sensor arrangement () for a tachometric sensor of an automatic transmission () of a motor vehicle, which encompasses a module carrier () in which a part of a sensor housing () is integrated. The sensor housing () is secured in the module carrier () or in the transmission housing () by way of a guide in the plane and is so affixed as to prevent turning and an apparatus () for the generation of a prestress force by way of which the sensor housing () is pressed in the direction of the signal disk by way of a projection (') acting against the sensor housing ().
