High Current Power Carbon Brushes Collector Ring IG280

Description

The carbon brush slip ring system is an important device for achieving stable transmission of energy and signals of rotating equipment. It consists of two parts: carbon brushes and slip rings. The carbon brush is made of graphite, etc., is soft in texture, and can maintain close contact with the slip ring. The slip ring is generally made of copper alloy, fixed on the rotating part, and rotates synchronously with the equipment. In the horizontal axis wind turbine, the carbon brush slip ring works together to extract the rotor electrical energy. Due to the sliding friction between the two, the carbon brush and slip ring are easy to wear, and regular inspection and maintenance are required to ensure the stable operation of the system.

Main Feature

a.Good conductivity: Carbon brushes are usually made of materials with excellent conductivity such as graphite, and collector rings are generally made of metals such as copper or copper alloys. These materials can ensure efficient transmission of current between the two and reduce energy loss.
b.Wear resistance: Since there is relative sliding friction between carbon brushes and collector rings during operation, they need to have good wear resistance to ensure stable performance after long-term use. Carbon brushes are treated with special formulas and processes to improve their wear resistance; the surface of the collector ring is finely processed and hardened to reduce the wear rate.
c.Good contact performance: In order to ensure the stability of current transmission, good contact needs to be maintained between carbon brushes and collector rings. Under the action of spring pressure, carbon brushes can fit tightly to the surface of the collector ring, and even in the case of equipment vibration or speed changes, they can maintain reliable electrical connection and reduce contact resistance and spark generation.
d.Adapt to high-speed rotation: In equipment such as wind turbines, the collector ring rotates at high speed with the rotor, which requires the carbon brush collector ring system to adapt to the high-speed working environment and have good dynamic balance performance and stability to ensure that there will be no loosening, jumping and other problems during high-speed rotation, which will affect the normal operation of the equipment.
e.Insulation performance: The collector ring and the motor shaft need to have good insulation performance to prevent current from leaking to the shaft, causing equipment failure or safety hazards. At the same time, components such as the carbon brush holder also need to have good insulation to avoid short circuits between carbon brushes and other non-conductive components.
h.Reliability and stability: The carbon brush collector ring system needs to maintain reliable performance in various harsh working environments (such as high temperature, humidity, dust, etc.), with high stability and anti-interference ability to ensure the stable operation of the entire motor system and reduce maintenance and downtime.

Application

Wind power generation: In horizontal axis wind turbines, carbon brush slip rings are used to transmit the electrical energy generated by the generator rotor to the stationary grid connection system. Since the rotor of the wind turbine is constantly rotating in the wind, the carbon brush slip ring needs to maintain a stable electrical connection at high speeds and in harsh outdoor environments to ensure efficient transmission of electrical energy.

Industrial motors: In various types of industrial motors, such as large DC motors, AC asynchronous motors, and synchronous motors, carbon brush slip rings are often used to introduce current from an external power source into the rotor winding, or to lead out the current generated by the rotor winding.

Power tools: Many power tools, such as hand drills, angle grinders, electric saws, etc., also use carbon brush slip rings in their internal motors.
Aerospace: Carbon brush slip rings play a key role in aircraft engines, aircraft generators, and various airborne electric equipment.
