A motor is provided to couple a PCB(Printed Circuit Board) with a stator assembly and to improve reliability of electrical connection by preventing damage to a coil in forming a mold unit. A motor includes a stator assembly(100), a PCB(200), and a rotor(310). The stator assembly has a stator and a mold unit. The stator has a hollow stator core and an insulator wound with a coil. The mold unit surrounds the stator core and the insulator. The PCB is received at an upper part of the stator assembly. The rotor is rotatably installed inside the stator assembly. The insulator has a positioning boss(118) which is exposed to an upper part of the mold unit to determine a position of the PCB. The PCB has a positioning hole corresponding to the positioning boss.
