Title:
AMORPHOUS DIVIDED-CORE STATOR AND AXIAL-GAP-TYPE MOTOR USING SAME
Document Type and Number:
WIPO Patent Application WO/2012/134114
Kind Code:
A2
Abstract:
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.
