A slip ring is an electromechanical device that enables the transfer of electrical current and data signals between a stationary component and a rotating part. It is also known as a conductive slip ring, brush, collector ring, rotating electrical joint, or electric rotor. These components are essential in various applications where continuous rotation is required, such as in industrial machinery, wind turbines, and robotic systems.
Collector rings are designed with excellent electrical conductivity, thermal resistance, and lubrication properties, along with sufficient mechanical strength and spark resistance. They are commonly used in DC motors and commutator motors, playing a critical role in current transmission and commutation. The durability of the collector ring directly impacts the motor’s overall lifespan, making it a vital element in motor performance.
1. The copper ring is manufactured through precision casting, offering high hardness, low electrical resistance, and superior wear resistance.
2. Insulating materials are typically made from epoxy resin combined with alkali-free glass fiber cloth, impregnated and laminated for enhanced insulation, compression resistance, impact resistance, and resistance to oil, oxidation, heat, and aging.
3. Custom specifications can be quickly developed and integrated with machines from around the world. The use of a starting resistor allows for step-by-step disconnection, enabling the optimal series resistor to maximize motor torque and reduce start-up time.
The hollow shaft slip ring is specifically designed with built-in hydraulic, pneumatic, or central holes for drive shaft installation, allowing compatibility with various electrical paths.
1. It utilizes advanced cluster brush technology with precious metal contacts, ensuring reliable performance under minimal friction conditions.
2. The company has mastered key design and manufacturing technologies, holds independent intellectual property rights, and fully supports 360-degree unlimited rotation for power and control signal transmission.
In addition, when the collector slip ring rotor is connected in series, it allows for speed adjustment. Prolonged operation of the radial collector ring can lead to wear, causing issues like keyway and key damage, which may result in excessive clearance between the shaft and the ring, leading to vibration. To address this, the radial collector ring should be removed, the keyway re-machined, and a new groove installed. If the inner diameter is severely worn, the entire radial collector ring must be replaced.
