<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 />
