Abstract:
1. 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 arc 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, wherein the locking portions protrude from the circumference and the hooks protrude from the inner sides of hook-formed steps depressed along the circumference to fit the locking portions, and wherein the locking portion has a locking groove stepped inside on the inner surface and inclinded sides chamfered at both sides where the locking groove is not formed, and the hook has an inverted triangular shape and is fitted in the locking groove such that the upper surface of the hook is restrained by the locking portion.
