‘Linear Motors’

An Engineeringtalk guide

Start with the news release Abssac torsion springs have linear spring rates from Abssac, which we summarised at the time by saying "Abssac supplies unwind and wind-up torsion springs with linear spring rates. ". Several months prior to that, we featured the news release Accelerometers obtain hazardous-area certification from Wilcoxon Research: "Wilcoxon Research has announced an additional intrinsically safe certification in accordance with IECEx requirements for six general-purpose accelerometers.".

In November 2009, we covered the news from WEG Electric Motors - take a look at WEG motors drive Brazilian theme-park attractions which says: "WEG motors, inverters and soft starters are allowing the safe operation of equipment at the Beto Carrero World theme park, located in Santa Catarina, Brazil. ".

Take a look also at the news release from Galil Motion Control, Galil controller aids border patrol surveillance, as well as Emerson installs controls at Korean plants from Emerson Process Management, and Rotary encoders provide 1nm and 2nm resolutions from Renishaw.
