Embodiment Construction

[0021] 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 devices include electrical machines for converting mechanical power into electricity and vice versa. The electric machine comprises a laminated stator core 102 provided with stator windings. The electric machine comprises a rotor comprising a central part or rotor shaft 117, a frame 103 and permanent magnets 104 mounted on the outer surface of the frame. Of course, it is also possible that the rotor shaft 117 and the frame 103 are a single, integral piece. The electromechanical device includes one or more gear stages in a power transmission path between a mechanical interface structure and a rotor of an electric ma...

Abstract

An electromechanical device comprising a mechanical interface structure (101) for connection to an external rotating element, an electric machine (102-104, 117) and a mechanical power transmission path between the mechanical interface structure and a rotor of the electric machine or a plurality of gear stages (105-112), wherein the electromechanical device further comprises bearing means (118, 119) for rotatably connecting the rotor (103) of the electric machine to the structure of the electromechanical device, the bearing means bearing Axial and radial forces of the rotor and at least partly bear axial and radial forces of a drive shaft (112) of a gear stage directly connected to the rotor.

Description

technical field [0001] The invention relates to an electromechanical device which is a combination of one or more gear stages and a rotating electrical machine. More precisely, the invention relates to the bearing configuration and structure of such electromechanical devices. Background technique [0002] In many power generation systems, depending on various design and construction aspects, it may be advantageous to connect a generator to a prime mover, such as a wind turbine, via a gearbox arranged to convert the prime mover's rotational speed to a speed suitable for generating electricity. machine speed range. 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 single ge...
