Abstract

A rotor assembly for an inductively electrically excited synchronous machine may include a hollow shaft, a rotor connected to the hollow shaft, and a secondary-side circuit of an energy transmitter. The secondary-side circuit may be arranged in a rotationally fixed manner in the rotor assembly. The secondary-side circuit may include a rectifier. The rectifier may include a printed circuit board and at least one electrical component part fastened to the printed circuit board and a secondary coil. The rectifier may be aligned transversely to an axis of rotation of the hollow shaft and may be arranged in a rotationally fixed manner in a cavity of the hollow shaft. The rectifier may include a cooling body abutting against the printed circuit board such that the cooling body faces away from the at least one electrical component part and transmits heat.
