Motor arrangement

A motor arrangement, in particular a planetary-gear motor arrangement, comprising:

• a motor shaft;
• a stator, and a rotor assembly, and a housing surrounding said stator and rotor assembly, wherein the stator is formed from a magnet arrangement, which has a number of electromagnets arranged in an annular manner, and at least one permanent magnet, which are arranged relative to one another in such a way that a closed magnetic flux with an axial magnetization direction in a magnetic field can be generated in at least one of the electromagnets, wherein the motor arrangement is designed with a single-stage gear in such a way that the stator provided with an axial external tooth system or a wobble element meshes in at least one axial external tooth system of the rotor assembly, wherein at least one of:
• an at least partially flexible element is arranged on a pinion between the rotor assembly (B3′ to B3VIII) and the motor shaft, and
• a braking element is arranged on a pinion, between the rotor assembly and the motor shaft.
