The core made by molding each segment of core shape is
implemented for coil winding by making insulator to fix and
assemble each segmented core shape of BLDC motor. Also, the
rotor assembles 4 poles of ferrite magnet. The assembling of
rotor and stator is put in housing jig to measure the motor quality.
The Fig. 3 shows the stator core after finishing the coil winding.
Each core of dot point is fixed by insulator. Fig. 4 shows the
rotor after finishing the magnet bonding.
