Abstract:
1. A fan motor for circulating cooled air, comprising: a stator assembly having a stator core having teeth ends protruded annularly outwardly and coils wound on the teeth ends of the stator core and molded out of resin to have a donut-like shape having a bearing insertion hole formed to be passed vertically through the center thereof; a bearing assembly adapted to be insertedly fixed into the bearing insertion hole of the stator assembly; and a rotor fan assembly having a rotor having a cup-shaped case, a rotor shaft formed in the center of the case in such a manner as to be passed vertically through the center of the case, and magnetic poles formed along the inner periphery of the case, and a fan having a hub coupled to the top end periphery of the rotor shaft of the rotor and blades disposed around the hub, such that the rotor shaft is rotatably supported against the bearing assembly to allow the magnetic poles of the rotor to be positioned opposite to the teeth ends of the stator assembly around the teeth ends of the stator assembly.
