Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Rotor with slip rings
The rotor consists of two halves (claw-poles) which engage each other. The halves are pressed onto the rotor shaft. There are twelve claws on the rotor, i.e twelve poles. One half consists of six north poles and the other half six south poles. The excitation winding is secured on the rotor shaft between the claw-pole halves. The excitation winding (also known as rotor winding) consists of a circular coil winding which is connected to the slip rings and surrounded by the claw-poles. The charge regulator supplies a current to the rotor winding through the brushes which lie against the slip rings. The greater the current in the rotor the stronger the magnetic field in the rotor becomes, and thus a greater current is generated in the stator windings.
