Rare earth sintered magnets for compact and high power motors

Motor, one of major parts of hybrid cars, is for driving electromagnetically, equipped with rotors with permanent magnets and it rotates synchronizing with a frequency of 3 phase AC. Hybrid cars require lighter motors with higher power. The permanent magnet used for them are neodymium* sintered magnets because they have strong magnetic force with compact body. The neodymium sintered magnets are expected to grow in markets where such motors with compact body and high performance are requird.
*Neodymium (Nd) = Rare earth metal. Atomic number 60. Atomic weight 144.2. Lanthanide.
