Abstract
A drive device. The drive device includes an electric machine arranged in a housing, a sensor unit which has at least one circuit board and is designed to detect a rotational position of a rotor of the electric machine, and a rod-shaped contact apparatus which has at least one conductor which is electrically connected to the circuit board and is or can be electrically connected to a controller. The conductor is electrically connected to the circuit board by a plug-in connection.
