MOTION CONTROL PRODUCTS is now the sole distributor for Servotecnica’s range of slip rings in the UK.
The main purpose of the slip ring is to transfer signals or electric power from a fixed structure to a movable one. It ensures continuous rotation and prevents the electrical conductors being stressed by mechanical torsion.
Slip rings are also known as electric rotary joints, and they consist of two parts. The outer part is called the Stator, because it is stationary, and the internal part is called the Rotor, as it rotates. However, the operation is reversible, i.e. the external part, which is normally fixed, can be made to rotate and, as a result, the internal part (which normally rotates) can be kept fixed.
Servotecnica has paid special attention to the design and manufacture of the two elements that come into contact: the brushes and rings. The design elements include selection of precious materials, their relative thickness, the geometry, and the careful selection of the bearings. Together, this can provide an estimated service life of up to 50 million rotations.
Servotecnica’s range starts with the “Capsule” series which are slip rings without a through bore and with diameters measuring from 12mm to 22mm and featuring from 3 to 56 circuits. The gold to gold technology, applied to the brushes and to the rings, ensures the transfer of high frequency signals as well as fieldbus transfers with a bandwidth up to 1G, used especially in video surveillance systems, medical and pharmaceutical industries.
The “Faston” series with 32mm and 45mm diameters and featuring 2 to 6 contacts, which can simultaneously transmit power and even analogue signals, are ideal for filling and flow packaging equipment which use rotary tables. This range also offers IP65 protection rating.
One of the most popular series is that of the “through-bore” slip rings, i.e. with through-hole measuring from 3mm up to 100mm diameter in the standard versions. It is possible to transmit very high power, even by connecting several contacts in parallel and to simultaneously carry digital, analogue and Fieldbus signals.
