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

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

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
