ABSTRACT:
An electric motor has a rotor body elastically mounted on the shaft, the elastic mounting being relatively rigid in the axial direction. The shaft has an annular projection fitting in a circumferential recess in the bore of the rotor body. An elastic layer having a thickness which is small compared to the height of the annular projection is arranged at least between the circumferential surfaces of the annular projection and recess, and at least one radially extending face of the projection and recess.
