Abstract (en)

[origin: WO2016023930A1] A brush-commutated direct-current motor comprises a stator having a plurality of exciter poles, a rotor which can be rotated relative to the stator about an axis of rotation, a plurality of pole teeth which are arranged on the rotor, and grooves arranged between the pole teeth, the pole teeth being separated from each other by the grooves along a circumferential direction about the axis of rotation. Coil windings are arranged on the pole teeth. A commutator is arranged on the rotor and has a plurality of lamellae, each coil winding being connected to one of the lamellae via a first connecting arm and to one of the other lamellae via a second connecting arm. Every pole tooth (Z1-Z9) carries a first coil winding (Z1I-Z9I) which is wound about the pole tooth (Z1-Z9) in a first direction of winding and a second coil winding (Z1r-Z9r) which is wound about the pole tooth (Z1-Z9) in a second direction of winding, which is opposite the first direction of winding, the first connecting arm (Zl1) and/or the second connecting arm (Zl2) of the first coil winding (Z1I-Z9I) being guided to a respective lamella (L1-L18) about at least one other pole tooth (Z1-Z9). In this manner, a brush-commutated direct-current motor is devised which can be produced in a simple manner utilizing the available space and which has a good operating behavior.
