Pancake Slip Ring

Pancake Slip Ring

Pancake slip ring is designed for the limited rotation system in height direction, which is a special kind of conductive slip ring actually. Its shape just like a platter and always design and structure is flat, so sometimes it could be named flat slip ring and platter slip ring. The rotor part of pan cake slip ring with use of coils of concentric ring to carry current signal, the brush distributes at the top of the concentric ring as the stator. Whereas, use insulation materials to insulate between ring and ring. As we know that, this flat disc electrical slip ring could accept comprehensive load, large and huge instruction size, also it enjoys the features of compact design, sensitive rotary, easy installation and maintenance.
