Abstract

The invention relates to an arrangement for acoustic decoupling of a stator of an electric motor having two substantially cylindrical decoupling rings disposed on both sides of the stator and concentric to a motor shaft, each fixed to a front side of the stator on one side and each fixed to a housing enclosing the stator on the other side, and comprising recesses on the circumferential surfaces thereof. The decoupling rings hold the stator in a centered position at a distance from the housing. The recesses allow targeted acoustic decoupling. The invention is particularly applicable for electric motors in steering systems for motor vehicles.
