The original slip rings of Xi’an Taifu Simar Motor are made through precision processing of cast copper, featuring high hardness, low resistance, and good wear resistance. The insulating material is formed by impregnation, pouring, and lamination of epoxy resin and alkali-free glass fiber cloth, with good insulation performance, high compressive and impact resistance. The resin is oil-resistant, oxidation-resistant, heat-resistant, and has good aging performance.
Overview of Motor Slip Rings
A slip ring is an electrical component responsible for connecting and transmitting energy and signals for rotating bodies. According to the transmission medium, slip rings are divided into electrical slip rings, fluid slip rings, and optical slip rings, which can also be commonly referred to as “rotary connection” or “rotary pass”. Slip rings are usually installed at the rotation center of the equipment and mainly consist of two parts: rotating and stationary. The rotating part is connected to the rotating structure of the equipment and rotates along with it, called the “rotor”, and the stationary part is connected to the energy source of the fixed structure of the equipment, called the “stator”.
Slip rings, also known as rotary electrical interfaces or electrical rotary joints, can be used in electrical systems that require unlimited continuous rotation to transmit power and data signals from the fixed structure to the rotating structure.
The overall slip ring relies on the principle of elastic lap, rolling lap, or sealing, as well as ingenious motion structure and sealing structure design, precise parts manufacturing and coordination, and reasonable material selection to form a stable and reliable rotary connection system. As long as the slip ring is attached to the infinitely rotating equipment, it can provide power energy to the rotating body, enabling it to perform other movements or detect the working conditions while in infinite rotary motion.
The background of the generation of motor slip rings
In modern times, in the high-end field of industrial equipment, there are often requirements for multiple relative movements such as revolution and rotation. That is, while the mechanical equipment rotates 360° continuously, the rotating body also requires multiple movements. Where there is movement, there is a need for energy, such as electrical energy, fluid pressure energy, etc. Sometimes, control signal sources are also needed, such as optical fiber signals, high-frequency signals, etc. Any electrical components that rotate relatively and continuously by 360° need to transmit different energy media such as functional power supplies, weak current signals, optical signals, air pressure, water pressure, and oil pressure to ensure that the electrical appliances can move freely during rotary motion. Rotating connection devices must be used. Traditional electrical slip rings
Also known as “collector rings” or “current collector rings”. Domestic mature design technology and mature manufacturing factories have existed for several decades, mainly transmitting large currents and adopting the technology of carbon brushes closely abutting copper rings. Disadvantage: Limited to transmitting large currents, and a large amount of carbon alloy powder is generated due to friction, requiring regular cleaning or replacement of carbon brushes. Due to the rapid development of modern precision electronics and precision electromechanical products, precision slip ring electrical slip rings have emerged. Originally dedicated to ultra-high-end fields such as aerospace, they are now widely used in civilian precision electronic and electrical equipment. Some series have been made into general electrical accessories.
Electrical slip rings, the most widely used in all slip ring series, are also known as brushes, carbon brushes, collector rings, current collector rings, current collector rings, rotary passes, and rotary electrical joints, dedicated to transmitting power and signal power when rotating continuously without restrictions. The stator and rotor parts respectively lead out wires to connect the power supply and terminal appliances of the fixed structure and the rotating structure and rotate along with them. According to the differences in their overall structure, they are divided into solid slip rings (dig a hole in the rotating body and install the slip ring) (as shown in the figure), hollow slip rings (install the slip ring on the rotating shaft) (as shown in the figure), as well as separated slip rings, flat disc slip rings, mercury slip rings, special-shaped slip rings, etc.
The uses of motor slip rings
Slip rings are mostly used in high-end industrial electrical equipment or precision electronic equipment with multi-functional, high-performance, high-precision, and multi-element continuous rotary motion, such as: aerospace equipment, radar communication equipment, medical equipment, automatic processing equipment, smelting equipment, mining equipment, cable equipment, amusement equipment, display equipment, intelligent cameras, chemical reaction kettles, crystal furnaces, wire stranding machines, wind turbines, mechanical arms, robots, shield machines, revolving doors, measuring instruments, model aircraft, special vehicles, special ships, etc. Slip rings provide reliable energy and signal transmission solutions for the realization of complex movements of these electromechanical equipment. It can also be said that slip rings are the symbol of advanced intelligent motion equipment.
Slip rings can also be fabricated into various special shapes according to usage conditions, and mixed to transmit power sources, light source slip rings, fluid pressure sources, or be assembled and used with other electrical components, such as: special-shaped, oversized shapes, conjoined gears, sprockets, belt pulleys, plugs, mixed power and light sources, mixed power and pressure fluids, equipped with optical, electrical, acoustic, temperature sensors, optical fiber transceivers, pressure gauges, pneumatic components, etc., combined into a multifunctional electrical component assembly to meet the special requirements of saving space and simplifying the design structure.
