Patent number: 10491075Abstract: A stator assembly is provided including (a) an inner frame structure having an annular shape with an inner circumferential edge and an outer circumferential edge, wherein the inner frame structure is formed around a center axis corresponding to an axial direction of the electric generator; and (b) an outer frame structure, which surrounds the inner frame structure and which, starting from the outer circumferential edge, includes two inclined annular walls which, along a radial direction, spread apart from each other such that in between a first inclined annular wall and the second inclined annular wall there is formed an accommodation space. Preferably, the inner frame structure and the outer frame structure are made from a single piece.Type: GrantFiled: March 20, 2017Date of Patent: November 26, 2019Assignee: SIEMENS GAMESA RENEWABLE ENERGY A/SInventors: Uffe Eriksen, Edom Lemma, Claus Thygesen

Patent number: 10454342Abstract: An electric generator is provided including a stator assembly, a rotor assembly being rotatably supported at the stator assembly for rotating around a rotational axis, an annular device being fixed to the rotor assembly and including an engagement structure, and a first turning device being mounted to the stator assembly, the first turning device including an actuator and an engagement element being drivable by the actuator. The first turning device is configured for adopting two operational states, an active operational state and a passive operational state. In the active operational state there is an engagement between the engagement element and the engagement structure and in the passive operational state the engagement element and the engagement structure are mechanically decoupled from each other.Type: GrantFiled: March 27, 2017Date of Patent: October 22, 2019Assignee: SIEMENS GAMESA RENEWABLE ENERGY A/SInventors: Uffe Eriksen, Edom Lemma, Claus Thygesen

Patent number: 9303694Abstract: A bearing for a wind turbine, the use of the bearing and a method to control the temperature of the bearing is provided. A bearing for a wind turbine comprises an inner ring and an outer ring. The inner ring and the outer ring are prepared and arranged in a way to rotate with respect to each other. The inner ring comprises at least one channel. The channel is prepared and arranged in a way that air flows along inside the channel so that excess heat of the inner ring is removed by the airflow in the channel.Type: GrantFiled: May 19, 2014Date of Patent: April 5, 2016Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Uffe Eriksen, Claus Michaelsen, Claus Thygesen

Publication number: 20160084226Abstract: A wind turbine generator cooling system whereby the electrical generator includes a stator, a rotor, and an air gap between the stator and the rotor, and the rotor is rotatable in respect to the stator around an axis of rotation. The generator includes a cavity that is abutting on the stator in a radial direction, whereby a fan is connected to the cavity, so that the fan moves air through the cavity to cool the generator. A duct extends through the cavity in a mainly axial direction from a first side of the generator to a second side of the generator to allow the air that moves through the cavity, that cools the generator, and that collects at least partially at the first side of the generator, to flow from the first side of the generator to the second side of the generator to exit the generator.Type: ApplicationFiled: September 12, 2013Publication date: March 24, 2016Inventors: UFFE ERIKSEN, SOEREN GUNDTOFT, THORKIL MUNK-HANSEN, CLAUS THYGESEN
