Rotor with slip rings
The rotor consists of two halves (claw-type poles) that mesh with each other. They are pressed onto the rotor shaft, and the number of claws on the rotor is 12, i.e. there are 12 poles, with one half having six north poles and the other six south poles.
The excitation winding is fixed on the rotor shaft between the claw-type pole halves.
The excitation winding consists of a circular coil surrounded by the claw-type poles. An excitation voltage from the regulator is fed through the brushes, which are in contact with the slip rings.
