  • Device for continuous oscillation monitoring during rotating field machine operation
    Patent number: 11811270
    Abstract: A rotating field machine, in particular an electric motor with a stator and a rotor, is configured with a motor control for controlling the rotation and the rotational speed n of the rotor of the rotating field machine, wherein the motor control integrally includes an oscillation sensor system in order to acquire actual measurement values of oscillations of the rotating field machine depending on the rotational speed n.

  • Electric motor having improved cooling
    Patent number: 10734865
    Abstract: The invention relates to an electric motor comprising an electronics housing having motor electronics accommodated therein and a stator housing arranged axially at a distance from the electronics housing, wherein, axially between the electronics housing and the stator housing there is arranged a twin-flow cooling wheel which, during operation, generates a first cooling air stream along the electronics housing and a second cooling air stream along the stator housing and/or at least one bearing shield adjoining the stator housing axially.
