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.
Claims8
A brushless DC motor, comprising:
- an insulator that is combined with a stator to insulate a coil wound around a stator core of the stator and has at least one or more locking portions formed along the circumference;
- an outlet connector that has a terminal boss at a side where magnet wires led from the coil are positioned and the same number of hooks fitted and locked in the inner sides of the locking portions, when being combined with the insulator;
- and
- first, second, and third terminals that are positioned at first, second, and third position holes making a pair on the terminal boss and have retaining ends where the ends of first, second, and third magnet wires led from the coil to be fitted in the first, second, and third position holes are positioned and spot-welded.
