A brushless DC motor having a printed circuit coil is provided to improve assemblage and quality by preventing gap non-uniformity due to attraction force between a yoke and a magnet. A brushless DC motor(100) having a printed circuit coil(110) includes the printed circuit coil, a rotation shaft(120), a yoke(130), and a rotor(140). The rotation shaft is installed to be rotatable from the printed circuit coil. The printed circuit coil generates magnetic force by forming a pattern operated as a wound motor coil. The yoke is fixed to the shaft and is positioned at one side of the printed circuit coil. The rotor is fixed to the rotation shaft. The magnet is installed to face the printed circuit coil. The rotor is rotated by magnetic force generated in the printed circuit coil and an induction current generated by magnetic flux of the magnet.
