<strong>Slip</strong> <strong>rings</strong><br />

<strong>Scudo</strong> <strong>–</strong> <strong>Prisma</strong> - <strong>Navale</strong> <strong>series</strong><br />

Characteristics<br />

<strong>Slip</strong> <strong>rings</strong> are used to transfer electrical<br />

signal and power energy between a stator<br />

(stationary portion of the slip ring)<br />

and a rotor. They are comprised of 3<br />

or more graphite or metal contacts (brush)<br />

which rubs on the outside diameter of 3<br />

or more metal <strong>rings</strong>. As the metal <strong>rings</strong> turn,<br />

the electrical current or signal<br />

is conducted through the brushes<br />

to the metal <strong>rings</strong> making the connection.<br />

Both parts can be either stator or rotor<br />

indifferently. Brushes are available in graphite<br />

(<strong>Prisma</strong> and <strong>Navale</strong> <strong>series</strong>) or copper (<strong>Scudo</strong><br />

<strong>series</strong>) and can all be easily replaced.<br />

OPERATING LIFE<br />

The operating life of a slip ring is dependant<br />

upon the rotation speed and the dynamic<br />

stability. Hence it is important to make sure<br />

to avoid vibration of the rotor.<br />

CURRENT RATING<br />

Capacity can be increasing by connecting<br />

in <strong>series</strong> or parallel two or more slip <strong>rings</strong>.<br />

GRAPHITE COLLECTORS<br />

They are mainly used on low-medium speed<br />

applications. They are the most common<br />

in particular when more circuits are required<br />

as they ensure a very good connection,<br />

they withstand low and high temperatures,<br />

aggressive environments with presence<br />

of chemicals and humidity.<br />
