PURPOSE: The fan motor is provided to prevent contaminations of internal components by preventing oil from scattering efficiently while high speed rotating. CONSTITUTION: The motor includes a shaft(30) fixed at the center of the fan motor, and plural wings(21) installed at the outer, a blade(20) with a magnet inside, a holder(40) to support slipping through a bearing(B) on the shaft(30), a stator(50) with a core(51) and a coil(52) at the outer of holder(40) corresponding to the magnet, a circuit board equipped to be supplied power at the outer of the holder(40) on the stator(50), a thrust washer(60) to support load in the direction of the thrust contacting a part of the shaft(30) inside, and a thrust plate(70) formed a plural air drain grooves. A flue to pass through the atmosphere is at one side of the air drain groove.
