  • Patent number: 6144133
    Abstract: A direct current electromotor, having in particular small dimensions, comprising a collector plate arranged on a shaft, a plurality of collector wires held by the collector plate plate and accumulated to a collector sleeve, and comprising a capacitor disk also arranged in the area of the collector plate, the contact pads of the capacitor disk are each in electrical connection to at least one associated collector wire in a respective coordination. A direct current motor of this kind shall have a more simple structure so that very small diameters can also be produced. This is achieved in that the capacitor disk with its contact pads is directly set onto the collector wires and is connected therewith.
