The mysteries of slip rings
A slip ring (in electrical engineering terms) is a method of making an electrical connection through a rotating assembly. Slip rings, also called rotary electrical interfaces, rotating electrical connectors, collectors, swivels, or electrical rotary joints, are commonly found in all rotary systems with electrical connections of sensors and receptors. They are a common building block in terrestrial and space applications, e.g. wind turbines, computer tomography scanners, solar arrays in space and many more. Tribological characterization [...]
