Slip Rings: Technical Questions by Customers
Latest company news about Slip Rings: Technical Questions by Customers

1. Can we DIY slip ring by ourselves?


Some of our customers' DIY slip rings by themselves before but happened quality problems during operation. The slip ring is made of two parts-rotor and stator which use precious metal contacting materials inside. When you make a slip ring, you need to use a fixed bracket, bearing and some necessary parts that can be easy to implement. But here we need to remind that the design and technology manufacture of these large parts will affect the life and transmission performance of the slip ring. So we should pay much attention to the quality of the materials. Then what is the standard of these materials quality?

Firstly, slip ring contact materials mainly adopt copper and brass, also the surface of the slip ring need to plating layers of precious metals. This has played an important role in reducing resistance directly and extend the conductive slip ring lifetime to reduce electrical noise. Furthermore, these materials can directly ensure sufficient contact between the brush wire and copper ring. The most important factor for the homemade slip ring is for the requirement of process technology, also the production staff should have particularly professional knowledge about making a slip ring. As we all know, it is impossible to finish each production process and testing by one person. This must need a specialty technical team to accomplish the entire production chain. Although a self-made simple slip ring is feasible, we must know the technical requirements for different applications and then consider if you could do a homemade slip ring.

2. When do you have to replace slip rings?


The slip ring produced by JARCH enjoys the advantage of maintenance-free. That is to say, if your slip ring has reached a lifetime and could not operate anymore, then you need to change another new slip ring to replace. Normally, JARCH standard slip ring could meet around 50-80 million rotations which could satisfy with most of the customers’ lifetime demand. On another hand, if your slip ring happens quality matter in a short time, please contact the supplier to check and solve the problem in time.

3. What are wind turbine slip rings?


Wind turbine generator has different types and size, so the slip ring used in the wind turbine also has different design and dimension. For smaller wind turbines normally used capsule slip ring series for 22mm OD with 3 circuits each 15-30A current. This kind of slip ring design does not need high working speed but requires a longer lifetime. So we adopt gold plated contact materials to meet such demand and make sure smooth rotating. Big power wind turbine slip ring usually needs to be customized as per equipment’s special technical demand. The design always adopt carbon brush materials and silver-colored graphite or copper graphite contacting to guarantee reliable performance.

Wind power slip ring bears the function of power, control signal and data transmission in the whole system of the wind turbine systems. Wind turbine slip ring is the critical component in the fan system and its precision, reliability and working life directly affect the performance of the wind power system.
