- Vehicle height extension is used running and the external rotor to Drive the sunroof is used via the spiral cable connected to it. Compared to the prior art, this results in a significantly flatter or more compact design for the drive device in the direction of the vertical extension of the vehicle. In this way, an overall height z of the electric motor and thus of the entire drive device of, for example, 16 mm can be achieved - considerably flatter compared to the 33.8 mm or 30.00 mm in drive devices known from the prior art.
- the electric motor comprises in particular a stator and a rotor.
- the stationary part of a motor is usually referred to as the stator, which includes elements for generating alternating magnetic fields

- the rotor itself functions as a housing, that is, the output takes place directly via the rotor of the motor, which is designed as a housing.
- the worm wheel can also advantageously contribute to reducing the overall height, since the housing of the motor, which is always required in known devices to encapsulate and / or seal the motor, has its own thickness or fleas, which contributes to the overall height of the device.
- Manufacture of the external rotor and / or the worm wheel from plastic, in particular on contact surfaces with metallic elements of the drive device, can also contribute to reducing noise.
