Abstract

In a separately excited electrical synchronous machine, and a method for operating a synchronous machine, coil windings, in particular in the form of excitation coils, are disposed on the rotor, the electrical supply of the coil windings being achieved with the aid of an inductive rotation transmitter, whose secondary winding is connected to the rotor and whose primary winding, which is inductively coupled to the secondary winding, is stationary, especially connected to the stator of the synchronous machine.
