Magnetic Encoder Engine Technology An optical encoder uses light (optics) to identify unique positions for the encoder. A magnetic encoder uses the same principle to determine a position as an optical encoder, but it does it using magnetic fields rather than light. With a magnetic encoder, a large magnetized wheel spins over a plate of [...]
Simulating Permanent Magnet Generators Permanent magnet generators, or PM generators as they are also called, generate power without batteries. PM generators consist of a magnetic stator coiled with wire and a wheel with permanent magnets rotating inside the stator. From motorcycles to wind farms, PM generators can be used in many electrical machinery applications. Let’s [...]
Permanent Magnet Materials Permanent magnet lodestones contain magnetite, a hard, crystalline iron ferrite mineral that derives its magnetism from the effect the earth's magnetic field has on it. Various steel alloys can also be magnetized. The first big step in developing more effective permanent magnet materials came in the 1930s with the development of Alnico [...]
Magnet Background A magnet is a material that can exert a noticeable force on other materials without actually contacting them. This force is known as a magnetic force and may either attract or repel. While all known materials exert some sort of magnetic force, it is so small in most materials that it is not [...]
History of Permanent Magnets Lodestones The history of permanent magnets goes back to ancient times. Records from early Greek, Roman and Chinese civilisations make reference to rare and mysterious stones called lodestones. These lodestones could attract each other and also small pieces of iron. When suspended from a thread it was noted that they always [...]
The Manufacturing Process of Sintered Neodymium Magnet - How Neodym Magnets are made? Sintered neodymium magnet is manufactured by vacuum powder metallurgy process. The manufacturing process is as follows: 1. Raw Material Neodymium (Nd), Iron (Fe), Boron (B) and other addictives are measured according to the preferred element composition. Raw NdFeB material Raw Material of [...]
How to Choose the Bushless Motor Magnets? After you choose the slots and poles, you need to choose the magnets. This is not very easy task because you need high temperature magnets and are not so cheap and easy to find for your needed size. I bought custom made magnets from a Chinese SUPPLIER MPCO [...]
Grain Boundary Diffusion- Conserving HREE in NdFeB Magnets Grain Boundary Diffusion is an important new advance in Neodymium magnet production technology. Heavy Rare Earth Elements (HREE) are delivered directly to critical areas of the magnet’s microstructure. These areas are where HREE are the most effective at increasing the properties of the magnet to withstand high [...]
This is a list of rare earth elements (REEs), which are a special group of metals. Key Takeaways: List of Rare Earth Elements The rare earth elements (REEs) or rare earth metals (REMs) are a group of metals found within the same ores and possessing similar chemical properties. Scientists and engineers disagree on exactly which [...]
Investigation of magnet segmentation techniques for eddy current losses reduction in permanent magnets electrical machines Reducing eddy current losses in magnets of electrical machines can be obtained by means of several techniques. The magnet segmentation is the most popular one. It imposes the least restrictions on machine performances. This paper investigates the effectiveness of the [...]
How Magnet Therapy Work - Bio Magnet Magnets therapy in China – Last one year we are researching how to control Pain through natural therapy. Finally we found Magnet Therapy for Pain Relief. There are several ways to block the transmission of the pain impulse to the brain. One is the use of an anesthetic [...]
