Xi'an Xima Motor Original Slip Ring

The original slip ring of Xi'an Xima Motor uses precision-machined cast copper, which provides high hardness, low resistance, and wear resistance. The insulating material is selected from epoxy resin and alkali-free fiberglass cloth, impregnated and molded into a laminated form. It has excellent insulating properties, is pressure and impact resistant, oil-resistant, oxidation-resistant, heat-resistant, and has good aging resistance.

Overview of the Motor Slip Ring

A slip ring is an electrical component responsible for transmitting energy and signals to the rotating part. Based on the transmission medium, slip rings can be classified into electrical slip rings, fluid slip rings, and optical slip rings, commonly referred to as "rotary connections" or "rotary unions." A slip ring is typically installed at the rotational center of the equipment and consists of two main parts: the rotating part, which is connected to the rotating structure and moves with it (referred to as the "rotor"), and the stationary part, which is connected to the fixed structure of the energy supply (referred to as the "stator").

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

The slip ring operates based on principles such as spring overlap, rolling overlap, or sealing, combined with ingenious design for motion and sealing structures, precise component manufacturing, and careful material selection. These features create a stable and reliable rotary connection system. By attaching the slip ring to an endlessly rotating device, it can provide power to the rotating part, enabling the device to not only rotate indefinitely but also perform other movements or monitor its operating status.

Background of Motor Slip Rings

In modern high-end industrial equipment, there are often requirements for multiple types of relative motion, such as orbital motion or rotational motion. Specifically, when a mechanical device needs to rotate 360° continuously, the rotating part also requires multi-directional movement. Movement requires energy, such as electrical power, fluid pressure, and more. Sometimes, control signals, like fiber-optic signals or high-frequency signals, are also needed. Any electrical component that rotates continuously 360° and requires the transmission of various energy sources, such as power, weak electrical signals, light signals, air pressure, water pressure, oil pressure, etc., must use a rotary union.

Traditional Electric Slip Rings

Also known as "collecting rings" or "commutator rings," traditional electric slip rings have been in use in China for decades, with mature design technologies and production factories primarily designed to transmit high current using carbon brushes in contact with copper rings. The disadvantages include limitations to transmitting high currents and the need to regularly clean or replace carbon brushes due to wear from friction.

With the rapid development of precision electronics and electromechanical products, precision electric slip rings have emerged, initially designed for high-end fields such as aerospace. These slip rings are now widely used in consumer precision electronics and electrical equipment. Some models have become common electrical components.

Electric slip rings are the most widely used in all slip ring series. They are also called carbon brushes, commutator rings, collecting rings, or rotary electrical joints, specifically used for transmitting power and signal sources during continuous rotation. The stator and rotor parts connect electrical power to the fixed and rotating structures and rotate along with them. Based on their structure, slip rings can be categorized into solid circular slip rings (where a hole is drilled into the rotating body to install the slip ring), hollow circular slip rings (installed on the rotating shaft), as well as separate slip rings, flat slip rings, mercury slip rings, and special slip rings.

Applications of Motor Slip Rings

Slip rings are used in high-end industrial electrical equipment or precision electronic devices that require multi-functional, high-performance, high-precision, continuous rotational motion, such as aerospace equipment, radar communication devices, medical equipment, automatic processing equipment, smelting equipment, mining equipment, cable equipment, amusement devices, display equipment, smart cameras, chemical reactors, crystal furnaces, wire twisting machines, wind turbines, robotic arms, tunnel boring machines, revolving doors, measuring instruments, model aircraft, special vehicles, and special ships. Slip rings provide reliable energy and signal transmission solutions for these electromechanical devices, ensuring complex movements are achieved. They can also be seen as a symbol of advanced intelligent motion equipment.

Slip rings can be customized into various special shapes based on the application, combining the transmission of electrical power, light sources, and fluid pressure. They can also be integrated with other electrical components, such as special shapes, oversized configurations, integrated gears, sprockets, pulleys, and combinations of electrical power and light sources, electrical power and pressure fluids. These can be assembled with sensors, fiber-optic transceivers, pressure gauges, pneumatic components, and more to create multifunctional electrical assemblies, meeting special requirements for saving space and simplifying design structures.
