In view of the possible irreversible demagnetization problem of ferrite permanent magne-assisted synchronous reluctance motor, ferrite and NdFeB hybrid permanet magnet assisted synchronos reluctance for electric vehicle is studied. The rotor sturcture of hybrid permanent magnet assisted synchro
+New application of the radial multipole magnetic hard ferrite ring A new application of the radial multipole magnetic hard ferrite ring: the ring whose magnetic flux densit is sine wave shape on the surface, is made by new technology. Its magnetic property can reach about 210mT. Using
+Neodymium and /or parseodymium metal are the primary raw material in SPN . They are alloyed with iron and boron prior to being processed inoto a powder, which is the precursor to NdFeB bonded magnets. Other elements (such as zirconium or cobalt) are sometimes added to the alloy in small quantities
+Rare earths are a set of elements known as lanthanides found at the bottom of the periodic table, whose unique properties make them essential to many electronic, optical, magnetic and catalytic applications. The rare earths consist of yttrium and the 15 lanthanide elements (lanthanum, cerium, praseo
+Hard ferrite magnets are manufactured from iron oxide and either barium carbonate or strontium carbonate. The raw materials are mixed in the correct proportions, granulated, and calcined (presintered). After going through several intermediate phases, a hexaferrite phase (BaFe12O19 or SrFe12O19) is a
+Nd-Fe-B magnets have a higher Maximum Energy Product, (BH)max, than Sm-Co magnets. (BH) max of Nd-Fe-B can easily reach 30 MGOe and even goes up to 48 MGOe. Nd-Fe-B magnets can replace Sm-Co magnets in most cases, especially where operating temperature is less than 80 degrees Centigrade. The tempera
+Ceramic magnets are composed of iron oxide, barium and strontium elements. This class of magnets has a higher magnetic flux density, higher coercive force, and higher resistance to demagnetization and oxidation compared to other non-rare earth permanent magnets. The biggest advantage of such magnets
