PURPOSE: A brushless DC motor having auxiliary wire added to an armature wire is provided to improve a torque constant and efficiency of a motor by winding an auxiliary wire around a connection portion between tooth of the slot stator. CONSTITUTION: A slot stator(10) is formed by connecting 9 teeth(11) to each other. A main wire(20) is wound around 9 teeth(11). An auxiliary wire(21) is wound around connection portions among the teeth of the slot stator(10). A permanent magnet rotator(40) of 12 poles is located at a predetermined aperture(30) from the slot stator(10). A phase A(50) is formed by performing a winding process according to an order of a tooth A1(11a), a tooth A1'(11a'), a tooth A2(11b), a tooth A2'(11b'), a tooth A3(11c), and a tooth A3'(11c'). A phase B(60) is formed by performing the winding process according to an order of a tooth B1(11d), a tooth B1'(11d'), a tooth B2(11e), a tooth B2'(11e'), a tooth B3(11f), and a tooth B3'(11f'). A phase C(70) is formed by performing the winding process according to an order of a tooth C1(11g), a tooth C1'(11g'), a tooth C2(11h), a tooth C2'(11h'), a tooth C3(11i), and a tooth C3'(11i').
