source:GirstAt a laboratory inside a Google data center in Mayes County, Oklahoma, researchers spent the fall of 2019 disassembling old hard disk drives by hand in order to extract a 2-inch-long component known as the magnet assembly. Consisting of two powerful rare earth magnets, the magnet assembly is a critical muscle within the hard drive, controlling an actuator arm that allows the device to read and write data. Over the course of six weeks, the scientists harvested 6,100 of these magnetic muscles, all of them effectively good as new. The magnets were then shipped to a hard drive man...

source:ScienceParticle accelerators are very interesting in exploring the meaning of the universe, but they are, in our view, great tools – in some cases surrounding cities. Researchers have now developed a much smaller version of the advanced laser that will be just as effective as its larger counterparts.Question Particle Accelerator a Wakefield Plasma Accelerator, Which produces short, intense flashes of electrons, and is called the laser it uses Free electron laser (FEL) uses its own light to analyze atoms, molecules and compressed matter with incredible accuracy.Although this display has ...

source:WalesThat’s the message from Invertek Drives, one of the leaders in the innovation and manufacture of VFD technology, based at Welshpool, Powys.Announced on 14 July, the EC has set out its European Green Deal to reduce net greenhouse emissions by at least 55 per cent by 2030, compared to 1990 levels. This is part of delivering its European Climate Law which comes into force this month (July). The new law sets out tighter regulation on electric motors and VFDs.Around eight billion electric motors consume nearly 50 per cent of the electricity produced in Europe. Globally, 40 per cent of e...

New Magnetic Couplings From Miki Pulley “Mechanically Isolate” Shafts And Motor – They Provide Clean Operation In Mixing Systems source:AutomationworldMagnetic couplings from Miki Pulley are ideal for machine designs involving food, pharmaceutical and laboratory applications requiring clean, non-contact connection between motor and shafts.The mechanically isolated magnetic coupling transmits torque through the air. This occurs through both input and output hubs of the coupling which contain powerful rare-earth neodymium magnets. These magnets create a magnetic field that transmits torque ...
