    Abstract: A drive mechanism having a drive motor that rotatably drives a threaded spindle against a specific braking force generated by a pretensioned spring of a friction brake arrangement. The drive motor and the threaded spindle are arranged coaxially in a housing tube of the drive mechanism, and components of the friction brake arrangement are arranged in a tubular brake housing, which is arranged in an axially and rotationally fixed in the housing tube. A first end of the brake housing has one or more radially inwardly directed first stop shoulders and at a second end of the brake housing has one or more radially inwardly directed second stop shoulders. The brake housing has at its first end a radially circumferential ring with one or more radially resilient spring arms extending axially toward the second end, at the free ends of which spring arms are arranged the second stop shoulders.

    Abstract: An electric motor for driving a vehicle flap is provided, the electric motor including a hollow-cylindrical shaped stator made of a permanent-magnetic material and arranged coaxially to a motor axis, a motor shaft disposed coaxially with the motor axis and at least partially within the stator and mounted for rotation relative to the stator about the motor axis, and a drive rotor disposed within the stator and mounted on the motor shaft and including a plurality of coils for driving rotation of the motor shaft relative to the stator about the motor axis. The electric motor includes a braking rotor disposed in the stator, mounted on the motor shaft along the motor axis adjacent the drive rotor, the brake rotor being magnetisable by the stator. Use of the electric motor for driving a vehicle flap and to a method of manufacturing the electric motor is also provided.
