Abstract
Disclosed is a BLDC motor, including: a stator which is provided with a plurality of teeth extending toward an inner side of a core and pole shoes each extending to be formed at radial inner end parts of the teeth; and rotors which are disposed at an inner side of the stator surrounded by the pole shoes while being spaced apart from the stator and have a plurality of permanent magnets coupled to cores thereof. Inner circumferential surfaces of the circumferential end parts of the pole shoe may be formed so that a distance of the inner circumferential surfaces of the circumferential end parts of the pole shoe from the outer circumferential surface of the rotor increases as the inner circumferential surfaces of the circumferential both end parts of the pole shoe is far away circumferentially from a central line CL of the pole shoe.
