Abstract:
1. An electromechanical device comprising: a mechanical interface structure for connecting to an external rotating element, an electrical machine, and one or more gear stages on a mechanical power transmission path between the mechanical interface structure and a rotor of the electrical machine, wherein the rotor of the electrical machine is supported by a frame of the gear stage directly connected to the rotor, wherein the device comprises two or more gear stages, and a stator of the electrical machine is supported by a frame of another of the gear stages not directly connected to the rotor, wherein the one or more gear stages consists of: a first planet-gear stage and a second planet-gear stage, a planet-wheel carrier of the first planet-gear stage constituting a part the mechanical interface structure, a sun gear shaft of the first planet-gear stage being connected to a planet-wheel carrier of the second planet-gear stage, and a sun gear shaft of the second planet-gear stage being connected to the rotor of the electrical machine.
