Abstract:
Provided are an amorphous split core stator, which maximizes an opposing area between a plurality of split cores and magnets, increases a fill factor of coils, and which is molded by using amorphous metallic powder to thereby minimize an eddy current loss (or a core loss), and an axial gap type motor using the same. The axial gap type amorphous split core motor includes: a rotating shaft whose both ends are rotatably supported; first and second annular yokes the center of each of which is combined with the rotating shaft and that are placed at an interval therebetween; first and second rotors having a plurality of magnets that are mounted on the inner surfaces of the first and second yokes with polarities opposite to each other; and a stator having a plurality of split cores that are placed between the first and second rotors and on each of which a coil is wound, in which the split cores are molded by using amorphous metallic powder.
