When one end of the mechanical part needs 360° unlimited continuous rotation, the wires connect from the fixed end to the rotating end. So that a wire winding and kinking problem caused. The conductive slip ring can be used as an electric rotary connector to solve this problem.
What are the types of slip rings?
Electrical slip rings can be classified by structure or using.
According to structure, we can see capsule slip ring, through hole slip ring, disc slip ring, etc.
According to using, we can see Ethernet slip ring, video slip ring, thermocouple signal slip ring, wind power slip ring and so on.
Question, How to select electric slip ring?
The standard universal type generally has a product catalog, we can select according to the overall size and electrical parameters.
Since the slip ring is generally adapted according to specific equipment, we can select through fill out technical requirements table which provided by manufacturer.
Which part of the slip ring is the rotor and which part is the stator?
In general, the inner part of the slip ring is the rotor, and the outer part is the stator.
But slip ring rotates bidirectional, the specific outer ring artificial rotor or the inner ring as the rotor, depending on your slip ring transmission connection.
What technical parameters should be provided when customizing slip rings?
① Rated voltage and rated current of power circuit and signal circuit;
② The number of channels, or the number of ring channels;
③ The type of signal (such as: analog signal, digital signal and signal frequency, transmission rate, etc.) and anti-interference requirements;
④ dimensions requirements;
⑤ Installation method;
⑥ Working speed;
⑦ Working temperature;
⑧ Protection grade;
Can the rotating slip ring be interference-proof when transmitting signals?
The inner space of the precise rotating slip ring is small, and the mutual inductance and mutual capacitance effect between the signals are large. Experienced manufacturers will comprehensively consider the slip ring structure and internal wiring, which can completely avoid the interference problem between the power and the ring signal, and prevent the electromagnetic interference from the outside world to the inside of the slip ring.
Electrical Slip Ring Question, What signals can the slip ring transmit?
There are many kinds of signals now, the requirements are complex. Slip ring Can transmit a variety of analog or digital signals, including a variety of commonly using
Digital Bus signals, such as :Inter Bus, CAN-bus, Profibus, etc.
Serial communication signals, such as RS422,RS485, etc.
Various PLC control signals, servo motor encoder signals, etc.
Digital/analog video, digital audio, 100 / Gigabit Ethernet signals;
Weak signals such as temperature and weight sensors;
Optical signal, microwave signal, etc.
