PURPOSE: A brushless direct current motor including a radial direction and an axial direction magnetic circuit is provided to reduce the whole loss of a motor using the radial direction and the axial direction magnetic circuit. CONSTITUTION: A permanent magnet(120) is attached to the inner wall of a hub(111). A rotor(110) includes a rotation shaft installed in the center of the hub. A coil(160) is attached to the inside of the hub. A stator(150) creates a magnetic field by electrically interworking with the permanent magnet. A core receives the created magnetic field generated from the permanent magnet. The magnetic field of a radial direction and an axial direction is generated by the permanent magnet and the coil. The created magnetic field is delivered to the radial direction and the axis direction of the core.
