Abstract
An encoder arrangement of a direct current motor, having an encoder housing, an encoder disk, a circuit board arranged perpendicular in reference to an motor shaft with an optic sensor encompassing the encoder disk in a U-shaped manner, and a connection plug aligned parallel to the motor shaft. The encoder arrangement allows a simple, economical, reliable, and precise assembly, requiring little construction space, and protecting the encoder arrangement from contaminations. The circuit board is provided with accepting slots for connectors, with contact surfaces of the circuit board being arranged partially around the accepting slots and an electric contact is made between the connectors and the contract surfaces. The encoder housing comprises an encoder housing ring and an encoder housing lid. The encoder housing ring is provided with a radial recess, which is arranged in the area of the connector plug. The optical sensor is arranged on the circuit board at the side of the connector plug, and is provided with an accepting slot for the encoder disk, which accepting slot being open towards the motor shaft on which the encoder disk is mounted. The accepting slots are open on the side of the direct current motor opposite the connection plug and towards the edge of the circuit board.
