Modular Control Systems for Wind Energy
For a 5-megawatt wind turbine prototype, aerodyn employs the latest control and software technologies, including a comprehensive PC-based control solution and the new modular TwinCAT Wind Framework. The TwinCAT Wind Framework features the latest software engineering and Big Data applications to extend current Industry 4.0 concepts to the wind energy industry. The modular software supports, for example, the direct provision of sensor data to the operator’s database, and in general enables the easy adaption of the wind turbine operation management to future requirements.

The Meaning of Life
End users and OEMs frequently specify "lubed-for-life" mounted bearings, thinking the lubed-for-life bearings will deliver the same life — without lubrication — as bearings that currently require periodic lubrication. The truth is it depends on many factors, and only a detailed review of the application and testing will provide a more accurate answer.

2016 Motion, Drive & Automation Show Everybody Loves US
The U.S. is a very attractive market for international firms with manufacturing solutions, and we see that trend continuing. This year (Hannover Fairs USA has) secured a tremendous amount of interest from international exhibitors and attendees, which demonstrate growing interest in the U.S. manufacturing sector.

FZG Gearboxes Lubricated with Different Formulations of Polyalphaolefin Wind Turbine Gear Oils
In order to analyze the different gear oils suitable for the lubrication of wind turbine gearboxes, five fully formulated ISO VG 320 gear oils were selected. In between the selected gear oils, four PAO base oils can be found: PAOR, PAOM, PAOC and PAOX. A mineral-based oil (MINR) was also included as reference.

Energized (Publishers Page)
Energy is the worldwide addiction of the human race. We can’t live without it, and no matter how much we try to conserve it, our appetite is insatiable.

Worm Gear Cutting (Ask the Expert)
I have a fairly straightforward question about a worm gear segment. But as of yet, I haven’t gotten a straight answer from any of the gear job shops I’ve approached about this job. Is there a "traditional" gear cutting method that can produce a ~180 degree enveloping worm gear segment when a feature on the back of the part will interfere with a complete rotation of the part? Or am I left with only the option of 4- or 5-axis surfacing with a CNC mill? I have presented this part to several well-known gear shops in the U.S. without a straight answer on how the part can be made. Any help you could offer would be appreciated.

Analyzing Wind Power (Bearing Briefs)
Wind is a form of solar energy. Winds are caused by the uneven heating of the atmosphere by the sun, the irregularities of the earth’s surface, and rotation of the earth. Wind Turbines convert the kinetic energy in wind into mechanical power.

Hertha Marks Ayrton (Power Play)
She was born Phoebe Sarah Marks April 28, 1854 in Portsea, Portsmouth, Hampshire, UK — the third child of a Polish-Jewish watchmaker named Levi Marks and Alice Theresa Moss, a seamstress. Her father died in 1861, leaving Sarah’s mother with seven children — and another on the way — and Sarah with shared responsibility for caring for the children.
