A BLDC motor easy to assemble with improved heat radiation performance includes: a shaft; top and bottom bearing joined to vertical ends of the shaft, respectively; a stator core mounted in a middle part of the shaft; a rotor covering the stator core; and a magnet mounted along an inner circumference of the rotor to be separated from the stator core. The rotor is divided into three sub portions separated from each other. The sub portions are capable of being joined and separated to/from each other. Caps are formed in upper and lower part of the stator core separately, thus an intake of foreign materials into the stator core is prevented and the internal heat radiation performance is improved. |
