Abstract:
1. A shock-resistant electrical machine, comprising: a housing elastically connected to a marine vessel; a unit, including a stator and a rotor, located in the housing and adapted to move with respect to the housing, wherein the rotor is connected to a propulsion shaft and the stator and rotor are at least one of radially and axially connected to one another with restricted play so as to be rotatable with respect to one another, wherein the unit is adapted to flex further with respect to the housing than a normal extent of noise-inducing vibration oscillation, wherein the rotor includes a tube shaped mounting body and an active part mounted on the mounting body, the rotor being elastically supported on the propulsion shaft, and wherein the stator is mounted on the mounting body of the rotor and is elastically supported on the housing.
