Leine Linde Systems presents new ADSR slip ring

Service planning made more efficient Onshore and offshore wind turbines are usually geographically distributed, and are therefore relatively far from service stations. As a result, unexpected servicing is incredibly involved and expensive. Wind turbine manufacturers, managers, and operators will benefit from the ADSR’s advanced diagnostic system, making it a smart solution for condition based maintenance

Wind Talk: UEA discusses slip ring reliability and aftermarket offerings

I’m Nic Sharpley, managing editor of Windpower Engineering & Development magazine. Welcome to another edition of Wind Talk, our podcast series that gives you the opportunity to hear from the industry’s newsmakers in their own words. We have Jesse Shearer, a design engineer with United Equipment Accessories (UEA), a manufacturer of custom components for motion

Leine Linde builds a slip ring with built-in rotary encoder for compliance with GL 2010 Guideline

Insurers, banks, and construction authorities usually require that wind-turbine manufacturers and operators have a certification according to the applicable guidelines. Up until now, the safety functions required within this context, for example, switching off wind turbines in case of excessive rotor speed, have been implemented with relatively costly and frequently redundant designs. With its new

UEA aftermarket slip ring makes Clippers more reliable

UEA has recently designed a new and improved slip ring for the aftermarket Clipper wind turbine. The new design has many improvements that make it more reliable, improve the sealing, remove the external wiring exposure, and enhance the communication circuits. With unknown and varying vibrations from turbine to turbine, as well as the rugged handling

Slip ring substitute promises no wear for life of turbine

A recent device that provides the function of conventional slip rings is said to outperform them with maintenance-free operation, low electrical resistance, low torque, and high shock tolerance. Instead of letting an arm slide on a conductive wheel, developer Diamond-Roltran (www.diamond-roltran.com) devised the system in which rings of spring copper roll between two conductive races

How are slip rings used in wind turbines?

Slip rings provide a reliable transmission of power and signals from stationary cables in the nacelle to rotating equipment in the hub. A slip-ring assembly is often a solid metal and graphite or precious-metal wire brush, which contacts the outside diameter of a rotating metal ring. As the ring turns, electrical current or signal conducts

Carbon brush holder promises reduced wind-turbine maintenance

An innovative carbon brush holder, set to reduce maintenance costs for doubly fed generators in wind turbines, will be introduced by Carbex at the AWEA WINDPOWER 2013 exhibition in Chicago, May 5 to 8 in booth 1011. Slip rings with carbon brushes are used for transferring power between the rotating and the stationary parts of

Moog earns TÜV Rheinland certification for safety on wind turbines

The Moog Pitch Servo Drive, a component of Moog’s Pitch System responsible for guaranteeing the safe operation of wind turbines, obtained a TÜV certification for compliance with the guideline issued by Germanischer Lloyd. This validates that Moog designs achieve Performance Level D for the wind turbine feathering safety function. The safety of wind turbines is

Slip ring company acquires seal manufacturer

Deublin Co. has acquired Barco Seals of Cary, Ill. Both companies manufacture fluid power components used in a variety of equipment and process industries. Founded in 1908, Barco developed swivels and ball joints for the railroad industry. Over the years, Barco developed and manufactured hundreds of rotating unions, plane, and self-aligning swivel joints. Deublin Co., founded

Slip rings for 70 million rotations

Morgan AM&T power slip rings are for OEM applications. Features include molded or build-up construction and rings of steel, stainless steel, bronze or brass. Hub control slip rings have a lifetime of 10 years or 70 million rotations and work five years without maintenance or lubrication. Their data transmission capacity is up to 400 MBd,
