- Such a drive device is known from DE 10 2005 055 740 A1 of the applicant.
- the known drive device comprises a
- Gear housing formed housing for receiving a
- End portions with the armature shaft is mounted in the housing, is the
- Circuit board limited exclusively to their function as a circuit carrier and therefore has no tasks beyond this function or
