1. A drive device for use in a motor vehicle, the drive device comprising:
a drive housing including a transmission housing and a motor housing connected to the transmission housing at a connection interface; and
a brushless electric motor configured to be mounted to the drive housing, wherein the brushless electric motor includes,
a stator provided with a stator body and a stator winding, wherein the stator body defines a central shaft passage and includes a number of external stator teeth arranged in a star formation, wherein the stator winding includes a number of phase terminals,
a rotor provided with a number of permanent magnets, a rotor shaft, and a rotor housing, the number of permanent magnets disposed in the rotor housing, wherein the rotor is an external rotor and the rotor housing surrounding the stator body and coupled to the rotor shaft, wherein the central shaft passage is configured to receive the rotor shaft;
a number of plug terminals including terminal contacts configured to receive a mating plug terminal,
wherein the number of plug terminals include a plug housing integrally formed with at least one of the transmission housing and the motor housing in a region of the connection interface, wherein the plug housing is configured to receive the terminal contacts,
wherein the terminal contacts are arranged in a terminal block defining an access opening configured to receive the phase terminals, and
wherein the number of phase terminals are disposed in a joining and/or contacting position to electrically contact the terminal contacts of the plug terminal.
