Beschreibung
Zusammenfassung:	An electric motor includes a generally tubular housing portion having an outer surface; a plurality of fixedly held support bases spaced circumferentially about the housing portion and being at a radial distance from the outer surface of the housing portion; and a plurality of elastic elements, each being secured to the outer surface of the housing portion and to a separate one of the support bases for supporting the electric motor by the housing portion and for suppressing excitation oscillations generated by the electric motor during operation thereof. The elastic elements together form a suspension system which is tuned to the excitation oscillations of the electric motor such that the natural frequency of the suspension system is less than the excitation frequency of the electric motor.
