Slip rings are characterized as a kind of electrical contacts, which are a conductive ring with brushes that fit snugly against it. Thanks to these brushes, the electricity generated in the rotating electric machine is supplied from one part of the circuit to another part by means of a sliding contact.

The operation of the alternator slip ring

As a rule, ERA brand Slip Ring, alternator are used in the case when electrical energy cannot be transmitted directly using special wires, for example, at the time of supply to a rotating shaft.

Like all other tools in a car, depending on the chosen technological solution, slip rings can be divided roughly into two types: concentric and longitudinal rings. As a rule, the material from which the slip rings are made is a hard metal. In some cases, slip rings can be coated also with a wear and environmental resistant coating, which can be gold-plated or silver. Today, there are also known cases when liquid-metal slip rings were put into operation, which are mercury current collectors that ensure the transfer of high currents and have low resistance.
