Industries use permanent magnets to sort and separate materials on a grand scale and in hard drives and motors on smaller scales. Neodymium, a rare-earth element, forms a powerfully magnetic alloy when in concert with iron and boron. Iron and steel are the most plentiful permanent magnets, but the list doesn’t end with them although nickel and cobalt are non-ferrous, they’re also permanent magnets. A permanent magnet is a magnet that doesn’t require an electric current to retain its magnetic properties. Let’s break it down, piece by piece-the name, that is. “Permanent magnet direct-current generator.” That’s a mouthful. But what is a permanent magnet DC generator, and how is it used in an industrial setting? We’ll take a look at one of the most indispensable pieces of equipment on construction sites, demolition sites, recycling facilities, and anywhere else where people work with machinery and metals to get the job done. This device is called a permanent magnet DC generator. By constructing a device that harnesses magnetism and movement, we can create and move a direct current of electricity straight to our electromagnets and other machinery. Powering them isn’t like plugging in a vacuum cleaner-running this machinery in the absence of a traditional alternating current requires you to get creative.Īs it happens, we can derive the power we need for electromagnets from some well-placed sets of permanent magnets. Where does that electricity come from? In many cases, it doesn’t come from a three-pronged plug, a wall socket, and more than a few yards of an extension cord. Electromagnets, of course, need electricity. Heavy industrial work needs electromagnets. Stokkermill Industrial Scrap Recycling Equipment.Railroad Equipment Suppliers and Repairs.
