Embodiment Construction

[0024] figure 1 A schematic cross-sectional view of an electromechanical device according to an advantageous exemplary embodiment of the invention is shown. The electromechanical device comprises a mechanical interface structure 101 for connection to an external rotating element, which can be, for example but not necessarily, a wind turbine. The electromechanical device includes an electric machine for converting mechanical power into electrical power or converting electrical power into mechanical power. The electric machine comprises a laminated stator core 102 provided with stator windings. The electric machine comprises a rotor comprising a central part 117, a frame 103 and permanent magnets 104 mounted on the outer surface of the frame. Of course, it is also possible that the central portion 117 and the frame 103 are a single integral piece. The electromechanical device includes one or more gear stages in the power transmission path between the mechanical interface stru...

Abstract

An electromechanical device comprises a mechanical interface structure (101) for connecting to an external rotating element, for example a wind turbine. The device comprises an electrical machine (102-104), and one or more gear stages (105-112) on a power transmission path between the mechanical interface structure and a rotor of the electrical machine. The device further comprises mechanical structures (113-115) constituting a common lubricant oil room for both the gear stages and the electrical machine. The electromechanical device comprises oil channels (116a) for directing lubricant oil circulated in the device to flow via the gear stages and via bearings (118, 119) of the electrical machine. Therefore, a common lubricating system can be used for both the gear stages and the electrical machine.

Description

technical field [0001] The invention relates to an electromechanical device which is a combination of one or more gear stages and a rotating electric machine. Background technique [0002] In many power generation systems, it may be advantageous from various design and construction points of view to connect the generator to a prime mover (such as a wind turbine) via a gearbox arranged to convert the rotational speed of the prime mover to Convert to speed range for generator. Accordingly, in many motor applications it may be advantageous to connect the electric motor to the actuator via a gearbox arranged to convert the rotational speed of the electric motor into a speed range suitable for the actuator. A gearbox may comprise one or more series of connected gear stages by means of which a desired gear ratio is achieved. Each individual gear stage can be, for example, a planetary gear stage or a spur gear stage. [0003] A challenging design aspect associated with the combi...
