PURPOSE: A BLDC motor is provided to prevent a short circuit between a circuit board and an excitation coil by soldering a reeled solder auxiliary part instead of the excitation coil in a printed circuit. CONSTITUTION: A motor housing forms an appearance. A stator includes a stator core and an excitation coil(220) made of aluminum. A rotor is rotatably arranged in the motor housing. A printed circuit board(400) is installed in the motor housing. A solder auxiliary part(500) improves a soldering performance between the printed circuit board and the excitation coil.
