‘Permanent Magnets’

An Engineeringtalk guide

Start with the news release Micro stepper motors bring pictures into focus from EMS, which we summarised at the time by saying "Electro Mechanical Systems has supplied Precistep micro-stepper motors to Life Optics to allow it to develop a compact, reliable and light-weight head-mounted microscope.". Several months prior to that, we featured the news release PCB sensor measures internal ballistics of guns from PCB Piezotronics: "The Aerospace and Defense division of PCB Piezotronics has introduced the Model 165B02 charge output pressure sensor to measure the internal ballistics of sporting, police and military shot guns.".
 
In November 2009, we covered the news from Ametek Technical and Industrial Products - take a look at DC motors engineered for transportation purposes which says: "Rotron brushless DC motors from Ametek, engineered for applications on board heavy-duty transit buses, coaches and other vehicles, deliver long-life power solutions serving up to 60,000 hours.".
 
Take a look also at the news release from Eriez Magnetics Europe, Eriez magnets/detectors installed in cement plant, as well as Zouch foamed acrylic tapes are visco-elastic from Zouch Converters, and Viscotec devises drive solution for dosage units from EMS.
