FAQs

A slip ring is an electromechanical device that allows the transmission of power and electrical signals from a stationary to a rotating structure.

A slip ring can be used in any electromechanical system that requires unrestrained, intermittent or continuous rotation while transmitting power and / or data. It can improve mechanical performance, simplify system operation and eliminate damage-prone wires dangling from movable joints.

The BGB range of robust standard slip rings lends itself to a multitude of application speeds. Barrel and face type units use phosphor bronze rings as standard within an insulation medium of thermoset glass-reinforced DMC based on unsaturated polyester resin.

A slip ring is a device used within a wind turbine to transfer electrical power from the turbine's generator to the electrical grid. It is a rotating electrical connector that allows for the continuous transmission of power from the stationary part of the turbine to the rotating part of the turbine. This allows the turbine to generate electricity without interruption.

A slip ring is an electrical device that allows the transmission of power and signals from a stationary to a rotating structure. It consists of a stationary graphite or metal contact brush which rubs on the outside diameter of a rotating metal ring. The brush makes physical contact with the metal ring, allowing electricity to pass through. The metal ring is typically made of copper, brass, or silver and is plated in a protective material such as gold or silver to prevent corrosion. The metal ring can also be insulated with an electrically insulating material such as nylon or polyurethane. Slip rings are often used in applications such as electric motors, cable reels, and medical equipment.

If you have a piece of equipment that rotates and has a requirement for electrical power or signals transferring between the rotary and stationary components of the assembly, then a slip ring would be a solution for your application.
 

If you contact BGB we will guide you through the process of specifying the relevant requirements and properties.
 

Slip rings vary in size according to the power transfer requirements and the application interface.
 

A slip ring transfers electricity via sliding contacts from a stationary to a rotary side of an electro-mechanical assembly.
 

Rings are generally produced in copper alloy, whilst brush contacts are commonly copper or silver graphite. The mechanical framework and housing can be manufactured in most suitable materials, with suitable surface protection where required.
 

Generally one ring is required for each conductor in the supply cables used in the application. If required additional rings may be incorporated for shielding purposes.
 

Depending on the application and the mechanical interface, the slip ring can be manufactured to customer specification
 

The slip ring generally is only limited by the space restrictions of the application.
 

Electrical circuits commonly requested to pass through a slip ring are, power, bus signals, encoder signals, etc.
 

The life span of a slip ring is dependent upon the contact materials employed, the operating environment, the rotational speed, vibration etc.
 

Depending on the duty cycle, it is normal to inspect a slip ring annually, and if required the unit should be cleaned and inspected for condition of rings and brushes.
 

No BGB do not supply mercury slip rings. Mercury is a poisonous chemical element we do not recommend using
 

Slip rings are also sometimes described as: Rotary Joints, Collector Columns, Commutator, and Electrical Swivel, rotary electrical interfaces, metal bands, rotating connectors, electric rotary joints or collector rings to name but a few
 

A FORJ is an acronym for Fibre Optic Rotary Joint. A FORJ enables the transfer of optical signals
 

A FORJ enables the transfer of optical signals from a stationary component to a rotary component of an application.
 

No a slip ring can be used whilst stationary, but this must be specified clearly.
 

Slip rings can be designed to incorporate rotary joints used for hydraulic, pneumatic or other gaseous requirements.
 

A gold wire slip ring is a device used to provide a continuous electrical connection between a stationary and a rotating component. It consists of a metal ring, typically made of gold, which is connected to a brush and brush holder assembly. The brush contacts the ring and the electrical connection is made. This device is commonly used in electrical motors, turntables and other devices that require a continuous connection.

Standard slip rings are also used to provide a continuous electrical connection between a stationary and a rotating component. However, instead of using a metal ring, they typically use a conductive plastic material to make the electrical connection. These devices are typically used in applications where space is at a premium, and the cost of gold wire slip rings is prohibitive.

Slip rings are used to transmit power and/or electrical signals from a stationary to a rotating structure. They are commonly used in applications such as electric motors, wind turbines, and robotics. Slip rings are used to maintain an uninterrupted power and signal connection between a stationary and a rotating structure while they are in motion.

Brush holders are electrical components used in motors to hold the carbon brushes in place. They provide a stable connection between the moving parts of the motor and the electrical power source. Brush holders also help to keep the brushes clean and reduce wear and tear on the motor.
