A BLDC(Brushless DC) motor is provided to suppress vibration and noise due to non-uniformity of a magnetic flux density of an air gap by implementing sine distribution of the magnetic flux density of the air gap. A BLDC motor includes a rotor(120) with permanent magnets(130) which are arranged on the same circumference in a circumferential direction to be separated from each other at predetermined intervals. The permanent magnets have thicknesses of both ends smaller than a center of a magnetic pole. The BLDC motor further includes a stator(110). The stator is positioned to have an air gap from the permanent magnets and includes teeth of which centers further protrude toward the permanent magnets in comparison with both ends. |
