Abstract
BLDC motor including a stator with teeth which extend toward an inner side of a core and have a coil wound therearound; rotors disposed at an inner side of the stator and spaced apart from each other having a plurality of permanent magnets coupled to a core thereof; and hall sensors disposed and spaced apart to be opposite to an outer circumferential surface of the core of the rotor and disposed within a height range between both surfaces in a height direction of the core of the rotor to detect a change in a magnetic field in response to a rotation of the rotor, thereby accurately grasping positional information of a rotor and accurately controlling a rotation of the rotor by transmitting a magnetic flux generated from a permanent magnet of the rotor to a hall sensor enabling the hall sensor to detect a change in a magnetic field.
