The Operating Principle and Internal Structure for Slip Ring The slip ring itself actually does not have the rotating function. Slip rings consist of two parts, one is for rotor that could connect the rotating structure in the equipment, another one is for stator which can connect the fix structure in the device. The design structure of rotor and stator are precise overlay of single channel, the circuits for overlay could be customized according to exact technical requirements. During assembling, slip ring supplier can make the circuit of stator side to be one-to-one correspondence with rotor side, which could be formed circuits between rotor and stator. In such case, the electrical performance for each channel can be independent and mutual noninterference. However, the circuit formation between stator and rotor should contact each other. Their contact is the functional location and the carrier of various performance of the total slip ring. Therefore, the contacting materials, suitable design and structure, precise technology all should be the significant factors for superior quality slip ring. Through the both end lead wires of slip ring, it can transmit all kinds of signals as needed under rotating condition.
