What Is a Slip Ring?

Slip rings are electrical components that are responsible for communicating and transmitting energy and signals for rotating bodies. According to the transmission medium, slip rings are divided into electric slip rings, fluid slip rings, and smooth rings. They can also be collectively referred to as "rotary communication" or "swivel". The slip ring is usually installed in the center of rotation of the equipment, and is mainly composed of two parts: rotating and stationary. The rotating part connects the rotating structure of the device and rotates with it, called "rotor", and the stationary part connects the energy of the fixed structure of the device, called "stator".

Slip rings, also known as rotary electrical interfaces and electrical rotary joints, can be used in any electrical system that requires a continuous structure to transmit power and data signals from a fixed structure to a rotating structure.

Utilizing sliding or rolling contact of conductive parts,

In modern times, in the high-end field of industrial equipment, there are many requirements for multiple relative motions such as revolution and rotation. That is, while the mechanical equipment rotates 360 ° continuously, multiple rotations are required on the rotating body. With exercise, energy is needed, such as electric energy, fluid pressure energy, and so on. Sometimes, you also need to control signal sources, such as fiber optic signals and high-frequency signals. Any electrical component that rotates 360 ° relatively continuously needs to transfer functional power,

Also known as "

Slip rings are mostly used in high-end industrial electrical equipment or precision electronic equipment with multiple functions, high performance, high precision, and multiple continuous rotary motion, such as aerospace equipment,

Conductive slip ring belongs to the category of electrical contact sliding connection application. It is also called slip ring, or rotary joint, rotary electrical interface, slip ring, current collector ring, return ring, coil, commutator, adapter. A precision power transmission device for the image, data signal and power transmission of a relative rotating mechanism. It is especially suitable for applications where there is no limit to continuous rotation, while power or data needs to be transmitted from a fixed position to a rotating position.

It consists of an elastic material-brush, sliding contact surface material-

Electric slip ring: As the name implies, electric slip ring is the most widely used slip ring in all slip ring series, also known as brush, carbon brush, current collector ring, current collector ring, bus ring, swivel, rotating electrical joint , Dedicated to transmitting power supply and signal power supply during unlimited continuous rotation. The stator and the rotor part respectively lead out the wires to connect the power source and the terminal appliance of the fixed structure and the rotating structure, and rotate with them. According to its overall structure, it is divided into a solid circular slip ring (dig a hole in the rotating body and install the slip ring), an empty circular slip ring (install the slip ring on the rotating shaft), and a separate slip ring, a flat disk slip ring, Mercury slip rings, special slip rings, etc.

Electric slip ring: It is the electrical component responsible for communicating and transmitting energy and signals for the rotating body. According to the transmission medium, slip rings are divided into electric slip rings, fluid slip rings and smooth rings. It can also be commonly referred to as "rotational communication" or "rotational communication". The slip ring is usually installed in the center of rotation of the equipment and consists of two parts: rotating and stationary. The rotating part connects the rotating structure of the device and rotates with it, called "rotor", and the stationary part connects the energy of the fixed structure of the device, called "stator". The slip ring as a whole relies on the principle of elastic overlap, rolling overlap, or sealing, as well as ingenious movement and sealing structure design, precise parts manufacturing, reasonable selection of materials, etc., to form a stable and reliable rotary communication system. As long as the slip ring is attached to the device that rotates indefinitely, it can provide power to the rotating body, so that the rotating body can perform other movements or detect the working condition in the rotating state while the rotating body moves indefinitely.

Qu's current collector solves historical problems of winding electromechanical brushes and slip rings

The best solution for high voltage and high power winding motor brush slip ring problem

Although the winding type asynchronous machine has significant advantages in starting and speed regulation, it has the fatal defects of slip rings and brushes. This is the biggest problem that has plagued the winding type asynchronous machine since the history of the asynchronous machine. A proper solution will not only affect the starting and speed control of the motor, but also that the motor will not run at all, and the harm to production can be imagined. It is because of this fatal flaw that the wire wound asynchronous machine causes the application to be greatly restricted and its advantages devalued. However, it has not been applied in many situations that should be adopted, and the usage rate is far lower than that of the squirrel cage asynchronous machine.

Qu's current collector is a high-tech product that Qu Weiqian led his Baoding North Speeding Company to invent, develop and produce, which is a current collecting device dedicated to solving traditional motors-slip rings and brushes. The fatal flaw of the 200-year-old traditional winding motor current collector is solved ^[1] .
