A BLDC motor reduces a manufacturing cost in comparison with the BLDC motor with a plate and a sensing magnet by sensing a position of a magnet through a magnetic material. A housing(110) and a bracket(120) are mutually connected. An axis of rotation(140) is supported by the housing and the bracket and is pivotally installed. A rotor(150) has a magnet(155) fixed to an outer circumference of the axis of rotation. A stator has a coil(165) fixed to the housing in a form covering rotor(160). A sensor(175) which senses the location of a magnet and is fixed to the bracket is installed in a PCB(Printed Circuit Board). A magnetic material(180) is fixed to the bracket. One side and other side of the magnetic material are installed to face the magnet and the sensor so that the polarity of the magnet is transmitted to the sensor.
