  • What are slip rings and why do some motors use them?

    The slip ring brushes, made of graphite, are connected to a resistive device, such as a rheostat. As the slip rings turn with the rotor, the brushes maintain constant contact with the rings and transfer the resistance to the rotor windings. Slip rings on a wound rotor AC motor. Once the motor reaches operating speed, the brushes are lifted via ...
