The present invention relates to an amorphous divided-core stator which maximizes the area between a plurality of divided cores and a magnet arranged opposite one another, increases the coil fill factor, and is formed using amorphous alloy powder to minimize eddy current losses (core losses), as well as to an axial-gap amorphous divided-core motor using same. The axial-gap amorphous divided-core motor includes: a rotating shaft, both ends of which are rotatably supported; first and second yokes, each having a circular shape, and each having central portions coupled to the rotating shaft, wherein the first and second yokes are disposed with a predetermined distance therebetween; first and second rotors including a plurality of magnets, the polarities of which opposite each other, on the inner surfaces of the first and second yokes; and a stator disposed between the first and second rotors, wherein the stator includes a plurality of divided cores around each of which a coils is wound.
Description
technical field [0001] The present invention relates to an amorphous split iron core stator and an axial gap motor using the stator, in particular to a coil filling factor (fill factor) which can maximize the facing area between a plurality of split iron cores and magnets. ), and with the assembly of a plurality of split cores through the concavo-convex joint between the bobbins, or through the assembly of auxiliary materials for fixing, insert injection molding can be omitted, so it is easy to manufacture, and it is also molded using amorphous alloy powder , Therefore, an amorphous split iron core stator capable of minimizing eddy current loss (core loss) and an axial gap type motor using the stator. Background technique [0002] Brushless DC (BLDC, brushless dc) motors are classified according to whether the stator core exists, and are generally divided into core type (or radial gap type) and coreless type (or axial gap type) with a cup (cylinder) structure type). [000...
