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.

Electric motor for driving a vehicle flap, use and method of manufacturing of the electric motor

A DC electric motor for driving a tailgate of a vehicle is provided, the DC electric motor including a rotor and a stator, the rotor being rotatably supported about an axis of rotation, at least one of the rotor and the stator having a magnetic asymmetry for generating an asymmetric magnetic interaction between the rotor and the stator, wherein the rotor and the stator are configured to assume first positions and second positions relative to each other, wherein a higher holding torque acts between the rotor and the stator in one of the first positions than in one of the second positions due to the asymmetry.
