ROTORELEMENT EINER ROTORLAGESENSORVORRICHTUNG, ROTORLAGESENSORVORRICHTUNG UND ELEKTRISCHE ROTATIONSMASCHINE

The invention relates to a rotor element of a rotor position sensor device, a rotor position sensor device equipped therewith, and an electrical rotating machine having a rotor position sensor device according to the invention. The invention relates to a rotor element (1) of a rotor position sensor device (70), which element is used to generate eddy currents in a sensor element (71) of the rotor position sensor device (70), wherein the rotor element (1) is substantially in the shape of a wheel and comprises a connection portion (11) in a radially inner region (10), which connection portion has an axially extending threaded portion for mechanical fastening on a shaft (30), and wherein the rotor element (1) has a closed circular profile (16) on its radially outer side (14). By means of the rotor element according to the invention, as well as the rotor position sensor device and the electrical rotating machines equipped therewith, apparatus is provided with which reliable information concerning the angular position and/or the rotational speed of the respective rotor can be determined while ensuring that the axial installation space needed is kept to a minimum.
