Abstract
A very simple and reliable rotor () for a (brushless) exciter to be used to energise the field winding of a rotor of a generator, is proposed which can be used for high-speed rotation and for the generation of high currents for energising the field winding of the rotor of the generator. The rotor () comprises at least two conducting bars () aligned substantially parallel to the axis () of the rotor (), wherein the bars () are connected on their first axial end to a collecting ring () and wherein on their second axial end the bars () are connected individually to two rings () by means of diodes () with reversed polarity such that alternating current induced in the conducting bars () due to a static field () is converted into a direct current (DC) in the two rings ().
