Abstract: A brushless direct current (BLDC) motor is disclosed. The BLDC motor includes a shaft made of a nonmagnetic material, a plurality of magnets surrounding the outer circumference of the shaft, a stator surrounding the outer circumferences of the magnets, wherein each of the magnets has an arc-shaped outer circumferential surface, an arc-shaped inner circumferential surface facing the shaft, and opposite side surfaces facing other adjacent magnets, and the magnets include a first magnet magnetized in a direction directed from the outer circumferential surface to the inner circumferential surface, a second magnet magnetized in a direction directed from the inner circumferential surface to the outer circumferential surface, and a third magnet magnetized in a direction directed from one side surface to the other side surface. The efficiency of the motor is improved while eddy current loss is minimized.
