Abstract

Die Erfindung betrifft eine elektrische Maschine, 5 insbesondere Elektromotor, mit einem Stator (6) und einem Rotor (5) und einer feststehenden Sensoreinrichtung (1-4) zum Erfassen der Relativlage zwischen Stator und Rotor, - wobei die Sensoreinrichtung ein Flussleitelement (3) und ein magnetisches Sensorelement (2) umfasst und über das 10 Flussleitelement der Magnetfluss eines mit dem Rotor (5) umlaufenden Magneten zum Sensorelement (2) leitbar ist, - wobei das Sensorelement (2) mit Abstand zum Rotor (5) angeordnet ist und ein sich zwischen dem Sensorelement (2) und dem Rotor (5) befindender Luftspalt von dem 15 Flussleitelement überbrückt wird, und - wobei das Sensorelement (2) unmittelbar an einer Leiterplatte (1) angeordnet ist . Dabei ist vorgesehen, dass das Flussleitelement möglichst einfach zu fertigen ist, indem es einen einzigen 20 ferromagnetischen Bolzen (3) aufweist, der parallel zur Rotationsachse des Rotors (5) angeordnet ist, wobei sich ein Ende des Bolzens (3) in unmittelbarer Nähe des Sensorelements (2) befindet.The invention relates to an electric machine, in particular an electric motor, with a stator (6) and a rotor (5) and a fixed sensor device (1-4) for detecting the relative position between stator and rotor, - wherein the sensor device is a flux guide element (3) and a magnetic sensor element (2) and the magnetic flux of a magnet rotating with the rotor (5) can be conducted to the sensor element (2) via the flux guide element, - wherein the sensor element (2) is arranged at a distance from the rotor (5) and the air gap located between the sensor element (2) and the rotor (5) is bridged by the flux guide element, and - wherein the sensor element (2) is arranged directly on a printed circuit board (1). It is provided that the flux guide is as simple as possible to manufacture by having a single ferromagnetic pin 20 (3) which is arranged parallel to the axis of rotation of the rotor (5), wherein one end of the bolt (3) in the immediate vicinity of Sensor element (2) is located.
