Absolute angle encoders have integral bearings, hollow shafts, and connect to Fanuc controls. Heidenhain’s RCN 2000, 5000, and 8000 series have diagnostic functions, plug-in cables with a quick disconnect at the encoder, and a variety of hollow shaft diameters. The encoders permit positive fastening, the company says. Compatible with the EnDat interface, the company says…
2012: Trends in encoders
Most double-fed induction generators require encoder feedback for top performance and line synchronization. But the high vibration and temperature extremes kill even “heavy duty” optical encoders. Recent encoders have been designed for wind turbine applications. The devices indicate the angular position of a rotating shaft and are often described as incremental or absolute. But there…
Thin encoder mounts directly to motor shafts
To meet the motor industry’s needs for a thin and reliable rotary encoder for tight spaces, Leine & Linde introduces the 700 Series. These encoders feature a thin design and a large hollow shaft of up to 25.4 mm which allows mounting them directly on a motor’s shaft without an intermediate adapter for shaft reduction.…
Whitepaper: Encoders shouldn’t fail, but what to do when they do
It should be obvious that the “heartbeat” of a process shouldn’t stop, leaving a machine without speed or distance feedback. But outputs occasionally do stop working for many OEM and industrial machines, leaving them with a complex troubleshooting question: Where did their encoder feedback go wrong? This article, written by Brian W. Winter, Encoder Product…
Non-magnetic encoders for high-magnetic fields
A company known for long-lasting miniature scales and small profile scanning units now manufactures a line of encoders that are non-magnetic. These linear and rotary encoders have been tested in environments up to six Tesla and have no influence on the machine environment. The encoders can also withstand a high magnetic environment without loss of…
Encoders 101
Most double-feed induction generators require encoder feedback for top performance and line synchronization. But the high vibration and temperature extremes kill even “heavy duty” optical encoders. Recent encoders have been designed for wind turbine applications. The devices indicate the angular position of a rotating shaft and are often described as incremental or absolute. But there…
Encoders slash downtime for generators
A line of encoders fit existing shafts and flanges while offering high durability. Avtron says its devices’ bearings are rated to over five times greater loads, and include magnetic sensors that shrug off dirt, grease, condensation, and oil. The encoders slash wind-turbine generator downtime while providing protection from all wiring errors. HS45 and AV45 add…
Generators need more durable encoders
Encoders serve an important purpose, so choosing the right one is an essential but complicated task. The device must work reliably, even in a tough environment. I’ve climbed a lot of turbines and can confidently say that wind applications are among the toughest around. With that in mind, think about where you’ll find encoders in…
