How can you prevent encoder failures in wind turbines?

Encoders are a forgotten component in wind turbines—at least until they fail. Wind turbines are a challenging application for encoders, something many OEMs and end-users discover just after installation. The constant vibration and thrust is tough on tiny encoder bearings (and for absolute encoders it’s tough on internal gearboxes). Another problem is temperature cycling combined

CUI announces new modular encoder series

CUI, Inc. has announced a modular encoder series that combines both accuracy and ruggedness. The AMT11 incremental encoder family is targeted at industrial applications, which are subject to vibration and contaminants such as dust, dirt, and oil that typically stop optical encoders from working effectively. This, when combined with exceptional accuracy figures of +/-5 arcmin,

Trends in encoders 2014

Wind turbines are a dickens of a place to expect electronics to work well. High vibration and temperature extremes kill even “heavy duty” optical encoders. To handle such loads, encoder manufacturers have designed units just for wind turbines. The devices are assigned to at least four applications in a wind turbine, depending on design. Generally,

Leine & Linde offers new stainless steel model 600 encoder for severe environments

Leine & Linde introduces a new stainless steel version of the well known ISA and IHA 600 series of absolute rotary encoders. Designed to provide motion control and feedback for machines in harsh environments, the IXA 600 stainless steel model is useful in applications where the encoder is subject to saltwater, acids, or other aggressive

Leine & Linde encoder meets needs of heavy equipment users

The Leine & Linde model PHE 900 encoder will meet the needs of the most demanding heavy equipment applications, and is currently experiencing particular interest from those in the mining and oil & gas industries.  This absolute encoder has been created as a flexible platform which can be tailored to meet various application requirements.  It

Heidenhain intros an absolute rotary encoders with functional safety

As demand for functionally safe equipment products grows, so does Heidenhain’s component product offerings. New to the market are Heidenhain’s ROx 400 absolute rotary encoders, available in a functionally safe design including a mechanical fault exclusion for the shaft. Both the synchro and clamping flange versions passed testing from TÜV Süd, an international service corporation

Baumer flexible magnetic belt encoder adapts to any shaft diameter

HDMag flex magnetic encoders from Baumer allow great flexibility in mounting and accurate measuring under harsh conditions on large shafts such as those in torque motors, generators, large drive units, azipod drive units (PODs), hoists and cranes, paper machinery, wind turbines, and hydroelectric plants. Available for shaft diameters from 300 mm (11.8 in.) to more

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

Leine & Linde encoder supports condition monitoring with PROFIBUS DP unit

So that machine builders can better monitor predictive motion controls, Leine & Linde introduce a new version of a rotary encoder supporting Condition Monitoring Systems.  The Model 862 is a heavy duty incremental encoder that further enhances plant efficiency with the PROFIBUS DP communication interface.  Leine & Linde’s Advanced Diagnostic System (ADS) includes the PROFIBUS

Improvements to nCode DesignLife allow solving problems on many processors and more

HBM announces the version 9.1 release of nCode DesignLife, a leading solution for CAE fatigue analysis applications. Users can now more quickly solve fatigue analysis problems by using High Performance Computing (HPC) environments. A new Safety Factor product option helps assess the durability of a wider range of components used in ground vehicle powertrain engineering
