  • Patent number: 10320273
    Abstract: A brush-commutated direct-current motor comprises a stator with a plurality of exciter poles, a rotor with a plurality of pole teeth, which is rotatable relative to the stator about an axis of rotation, grooves arranged between the pole teeth, and coil windings arranged on the pole teeth and a commutator which is arranged on the rotor and a plurality of lamellae to which the coil windings are connected. For manufacturing such direct-current motor the coil windings are arranged on the pole teeth in winding cycles, in each of which a coil winding is wound onto each pole tooth. It is provided that on each pole tooth a first coil winding wound around the pole tooth in a first winding direction and a second coil winding wound around the pole tooth in a second winding direction opposite to the first winding direction are arranged.

  • Patent number: 10148146
    Abstract: A brush-commutated direct-current motor comprises a stator which includes a plurality of exciter poles, a rotor rotatable relative to the stator about an axis of rotation, a plurality of pole teeth arranged on the rotor, and grooves arranged between the pole teeth, wherein the pole teeth are separated from each other by the grooves along a circumferential direction around the axis of rotation. On the pole teeth coil windings are arranged. A commutator is arranged on the rotor and includes a plurality of lamellae, wherein each coil winding is connected with one of the lamellae via a first connecting arm and is connected with another one of the lamellae via a second connecting arm.
