Abstract:
The present invention relates to a BLDC motor comprising: a stator, which has a plurality of teeth formed to extend to the inner side of a core and has coils wound around the teeth; a rotor arranged to be spaced from the inside of the stator and having a plurality of permanent magnets coupled to a core; and a hall sensor arranged to be spaced from the outer peripheral surface of the rotor core so as to face the same, and arranged within a height range between both surfaces of the rotor core in a height direction so as to sense a change in a magnetic field according to the rotation of the rotor, wherein a magnetic flux generated by the permanent magnets of the rotor can be sufficiently transmitted to the hall sensor, and thus the hall sensor can accurately sense a change in a magnetic field so as to enable the position information of the rotor to be accurately recognized, such that the rotation of the rotor can be accurately controlled.
