The unit has a permanent-energized direct current motor (4) with an armature (5) rotatably supported in a pole housing (9) with an electrically subjectable wire wound coil and a permanent magnet in a housing wall of the housing, where the armature is coupled with a main shaft (7) by a gear unit (6). The motor has permanent magnets provided at the wall, where the magnets stay in reciprocal effect with the armature and inserted into a plastic ring. A rare earth-connection is used as magnetic material e.g. Neodymium Iron Boron. The magnets are covered with a protective layer by nickel.
