Abstract: A BLDC motor server includes a stator configured in a hollow cylindrical shape and comprising a plurality of teeth around which a plurality of coils is wound to form an electromagnetic field, respectively; and a rotor configured in a cylindrical shape rotatable within the stator and comprising a plurality of permanent magnets, each having an arched section in which an outer circumference side is extended in both directions from a rotation center side, wherein the plurality of permanent magnets is disposed, so that facing outer surface portions of two permanent magnets neighboring each other are adjacent to each other, and wherein a width Wo of the outer circumference side of each permanent magnet is configured to be smaller than a width Wc of the rotation center side thereof. The BLDC motor may reduce a noise and a vibration as well as increasing an efficiency of the motor.
