Summary:The device has a standing part (1) provided with a primary winding (7), and a rotary part (2) rotating with a shaft and provided with a secondary winding (8). A front circular disk (12), a shell core (16) and a pin (17) are made of magnetic core material. The primary and secondary windings, the disk, the core and the pin form a transformer. All parts of the disk, the core and the pin are arranged at the standing part. Parts of a core material are arranged at the rotary part at locations of smaller mechanical load by centrifugal force. The secondary winding is an air gap winding. Eine Vorrichtung zur transformatorischen Energieübertragung auf eine rotierende Welle weist auf: einen stehenden Teil (1) mit einer Primärwicklung (7) und einen mit der Welle rotierendem Teil (2) mit einer Sekundärwicklung (8), sowie einen Transformatorkern aus Magnetkernmaterial, wobei die beiden Wicklungen (7, 8) und der Transformatorkern (12, 16, 17) einen Transformator bilden. Dabei sind alle Teile des Transformatorkerns (12, 16, 17) am stehenden Teil (1) angeordnet, oder Teile des Transformatorkerns (19) sind am rotierenden Teil (2) nur an Stellen geringer mechanischer Belastung durch Fliehkräfte angeordnet.
