1. A BLDC motor, comprising:

  • a stator provided with a plurality of teeth which extend toward an inner side of a core and have a coil wound therearound;

    a rotor disposed at an inner side of the stator to be spaced apart from each other and having a plurality of permanent magnets coupled to a core thereof; and

    hall sensors disposed while being spaced apart from each other 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,wherein an upper surface of the stator in an axial direction, in which the hall sensors are disposed, is flat, and the hall sensors are disposed between an upper surface of the core of the rotor and the upper surface of the stator in the axial direction.
