There is a steadily increasing need for high-quality data transmission in rotating applications in the wind power industry. Older technologies are gradually reaching their limits. As a result, wind turbines frequently grind to a halt and stop generating power. There are many reasons for this, but one of the most common is faulty data transmission for turbines’ pitch control, which until now has relied on conventional slip rings.
SPINNER has developed a solution to the problem. The new contactless rotary joints replace part of the slip ring, which then no longer rely on direct physical contact and therefore ensure fault-free transmission of Ethernet data in real time at a rate of 100 Mbit/s.
The electronic transmission system used is contactless and therefore requires no maintenance whatsoever. The electronics are designed to be completely immune to interference and comply with all relevant EMI standards. As a result, the problems that have plagued conventional slip ring systems – transmission errors and loss of data packets – now belong to the past.
