Abstract
An electromechanical device comprises a mechanical interface structure () for connecting to an external rotating element, for example a wind turbine. The device comprises an electrical machine (-), and one or more gear stages (-) on a power transmission path between the mechanical interface structure and a rotor of the electrical machine. The device further comprises mechanical structures (-) constituting a common lubricant oil room for both the gear stages and the electrical machine. The electromechanical device comprises oil channels () for directing lubricant oil circulated in the device to flow via the gear stages and via bearings () of the electrical machine. Therefore, a common lubricating system can be used for both the gear stages and the electrical machine.
