| 摘要 |
The invention relates to a drive arrangement for a rotational body device comprising a shaft which is held rotatably with respect to a rotational axis, a first bearing module and a second bearing module, each with at least one elastic support element for supporting the shaft, an electric motor with a stator and a rotor which is provided so as to be rotatable with respect to the stator and is connected in a rotationally fixed fashion to the shaft, an electrically actuable stabilisation device which acts on the rotor in such a way that interference forces acting on the shaft and the rotor during the rotation are counteracted, a housing which engages at least in certain sections around the stator and a sensor unit for sensing a rotation of the shaft with the stator held thereon, wherein at least the first bearing module provides a mass body which is held in a non-rotatable fashion with respect to rotational axis by means of the at least one elastic support element, and in that the shaft is supported in a rotatable fashion on the mass body by means of a bearing of the first bearing module. |
