Abstract
The present invention is characterized in that it does not require specific fastening tools, which causes breakage or defects, or bonding work, because a brushless DC motor includes an insulator that is inserted in a stator to insulate a coil wound with led magnet wires and has at least one or more locking portions with locking grooves stepped on the inner side along the circumference and an outlet connector that has hooks fitted in the locking protrusions when being assembled with the insulator such that the insulator and the outlet connector are assembled in fitting and locking ways in assembling.
