摘要:
Die Erfindung betrifft ein Verfahren zum Betrieb einer elektrischen Rotationsmaschine, insbesondere eines Turbogenerators, mit den Schritten: - Zuordnen von physikalischen Alterungsmechanismen zu Versagensmodi von Komponenten der elektrischen Rotationsmaschine (S1300), - Bestimmen von physikalisch hergeleiteten Lebensdauerzählgrößen für die jeweiligen Versagensmodi und Komponenten (S1400), - Bestimmen von Wertebereichen, in welchen sich die Lebensdauerzählgrößen befinden können (S1500), - Dimensionieren der Wertebereiche durch elektrisch und/odermechanische Berechnung, welche jedem Betriebszustand einen lebensdauerverbrauchenden Lastfaktor zuordnet (S1700), - Ermitteln von dynamischen Lebensdauerzählgrößen, welche die Nutzung der elektrischen Rotationsmaschine und/oder durchgeführte Wartungsmaßnahmen an der elektrischen Rotationsmaschine berücksichtigen (S1900), und - Ermitteln von dynamischen Ausfallrisiken für jede Einzelkomponente in Abhängigkeit von dynamischen Lebensdauerzählgrößen (S2000).
摘要:
A hybrid drive module including: a torque converter with a cover, an impeller and a turbine; a rotor for an electric motor; a hub non-rotatably connected to the rotor and the cover and including a circumferential surface and a plurality of protrusions extending radially outward from the circumferential surface; and an end plate disposed between the plurality of protrusions and the rotor and engaged with the end plate and the rotor. The plurality of protrusions is formed of a material forming the hub and restrains the end plate and the rotor, with respect to the hub, in an axial direction.

The invention relates to a method of adjusting a brush holder (41) of a slip ring and brush assembly comprising at least one slip ring (50) with a radius of curvature R. With the method a test tool (80) is used to simulate a brush in the brush holder with the important difference that the test tool is able to indicate to the operator whether full contact between the slip ring and the contact surface of the test tool is obtained.

The invention relates to a method for repairing an electric generator, preferably in a wind turbine generator (WTG), the electric generator (10) having a stator and a rotor (30) rotatably mounted relative to the stator. The method of repairing the electric generator provides a rotor connecting ring (40) with a first conductor assembly and a second conductor assembly in two different planes, each assembly with a plurality of conductive arc segments. Each of the first and the second plurality of conductive arc segments form a ring-like shape in their respective plane, both ring-like shapes being concentrical to the central shaft (132) when the rotor connecting ring is mounted. First electrical connections (50) from the central shaft connect to the rotor connecting ring for the multiple phases (K,L,M). Second electrical connections (60) further connect from the rotor connecting ring to the respective windings of the multiple phases (K,L,M) on the exterior part of the rotor facing the stator. The rotor connecting ring enhances rotational and thermal stability of the electric generator.
