Abstract
An electric-motor drive mechanism is proposed, with an electric motor (12) that has a brush holder (16, 116, 216) for containing brushes (15a, 15b) and at least one magnetic field sensor (18a, 18b, 118a, 218a) for detecting the magnetic field of a magnetic wheel (19) non-rotatably connected to the motor armature shaft (32) and an electronics housing (20) for containing an electronics mounting plate (24) for a set of motor output and/or control electronics. The electronics mounting plate (24, 124, 224) is disposed outside an electric motor pole pot housing (26) on a support (28, 128, 228) formed onto the brush holder (16, 116, 216) and that the at least one magnetic field sensor (18a, 18b, 118, 218) directly contacts the control electronics on the electronics mounting plate (24, 124, 224) by means of first inserted strip conductors (30a-1 . . . 30a-3, 30b-1 . . . 30b-3, 130, 230) that are guided in bundles and are at least partially integrated into the brush holder (16, 116, 216).
