1. A commutator-motor gear drive unit, having a rotor shaft defining an axial direction, comprising:
- a) a motor housing having a front-side housing flange;
b) a gear housing having a front-side housing flange;
c) an electronic housing; and
d) a printed-circuit board, said printed circuit boardi) including an integrated brush-holder plate for the commutator motor,ii) arranged essentially parallel to said front-side housing flange of said motor housing and said front-side housing flange of said gear housing,iii) arranged radially and axially within said motor housing and said gear housing, andiv) being tightly sealed off from external elements on a first axial side by said motor housing and said electronic housing, and on a second axial side by said gear housing.

Abstract
To integrate electronics with a drive unit, given a simple manufacturing or assembly, and a compact type of construction, a printed-circuit board, which accommodates the electronic components and which is designed, at the same time, as a brush-holder plate for the commutator motor, is arranged, together with an electronic housing, parallel to housing flanges of a motor housing, of a gear housing. The printed circuit board of the drive unit, and is covered on its one axial side by the motor housing and the electronic housing, and on its other axial side by the gear housing thereby protecting it from external elements.

20. A commutator-motor gear drive unit comprising:
-
a) a rotor shaft, i) defining an axis, having a first axial side and a second axial side; b) a gear housing, i) radially surrounding an axial section of said rotor shaft, ii) having an upper section and a radially extending lower section, and iii) having a flange surface defining a plane perpendicular to said axis; c) an electronic housing, i) having a first side facing said first axial side and being sealed against said flange surface of said gear housing, ii) having an upper section defining a void, iii) having a lower section defining a cup shaped shell extending towards said second axial side and open on an end facing said first axial side and iv) having a second side facing said second axial side; d) a motor housing, i) having a flange surface sealed against said second side of said electronic housing at said upper section of said electronic housing, and ii) radially surrounding said rotor shaft; and e) a printed circuit board, i) held on said electronic housing, and ii) sealed within a cavity defined by said gear housing, said electronic housing, and said motor housing.
