What is the slip ring?

    A slip ring is an electromechanical device that allows the transmission of power and electrical signals from a stationary structure to a rotating structure. Slip rings, also known as rotary electrical joints, collectors or electric rotary joints, can be used in any electromechanical system that requires unrestricted, intermittent or continuous rotation when transmitting power and/or data. It can improve mechanical performance, simplify system operation and eliminate easily damaged wires hanging on movable joints.

    Slip ring series synchronous motors and asynchronous motors, etc., which use collecting rings, are widely used in industrial departments, and most of them operate under various harsh conditions. Although these motors do not have the commutation effect of DC motors, like commutators, they also suffer from abnormal wear of collector rings or brushes, brush vibration and spark generation. Especially from the brush material, the slip ring brush not only uses graphite brush, but also sometimes uses metal graphite brush to improve the current density of the brush. Therefore, abnormal residual expansion and other factors must be considered. Even for high-speed motors such as turbine generators or motors operating in totally enclosed gas and hydrogen media, there are many problems.

    The material of collector ring requires high mechanical strength, good electrical conductor and corrosion resistance. When sliding contact with electric brush, it must have wear resistance and stable sliding contact characteristics. Generally, the steel collector ring has good wear resistance and high mechanical strength, so it is mostly used on synchronous motors with large wear difference of collector ring caused by polarity.
