  • Rotor for an electric machine having a sheet metal for securing a pole shoe to a shaft
    Patent number: 11101706
    Abstract: The invention relates to a rotor (3) for an electric rotating machine (1), in particular a synchronous machine (20), comprising a shaft (5) and at least one pole shoe (7). In order to keep overhead and costs low while achieving high reliability, according to the invention, a metal sheet (8) is placed between the shaft (5) and the pole shoe (7); said metal sheet (8) has a first contact area (12) that is in contact with a contact area (14) on the pole shoe (7), the metal sheet (8) and the pole shoe (7) being made of different materials.

  • Contactless motion sensor for a magnetic bearing
    Patent number: 10823585
    Abstract: A sensor apparatus for a magnetic bearing apparatus includes a motion sensor and a sensor ring which has the shape of a hollow cylinder and is intended to be connected to a shaft of an electrical rotating machine in a force-fitting manner, wherein the motion sensor is separated from the sensor ring by an air gap. In order to achieve a greater degree of reliability at high rotation speeds and ratings in comparison to the prior art, the sensor ring has a carrier ring composed of a first material and a sensor target composed of a second material.
