Motor

摘要

Disclosed is a motor including: a housing formed by means of insert injection molding in such a manner as to locate a stator assembly inside a mold, the stator assembly having a stator core, an upper insulator adapted to be coupled to the upper side of the stator core, and a lower insulator adapted to be coupled to the lower side of the stator core; a printed circuit board adapted to mount an integrated circuit device thereon; and at least one or more screws adapted to be inserted into screw holes formed on the top peripheral portion of the housing and having screw heads formed thereon, the screw heads being engagedly coupled to the peripheral portion of the end cover and the end portions of the screws being brought into contact with the stator core.

1. A motor comprising:
a housing formed by means of insert injection molding in such a manner as to locate a stator assembly inside a mold and having a hollow portion formed at the inside thereof and power terminal pins exposed above the hollow portion, the stator assembly having a stator core, an upper insulator adapted to be coupled to the upper side of the stator core, and a lower insulator adapted to be coupled to the lower side of the stator core; a printed circuit board adapted to mount an integrated circuit device thereon and having a shaft insertion hole formed at the center thereof and power terminal pin holes formed at the corresponding positions to the power terminal pins; an end cover adapted to be coupled to the housing in such a manner as to be located on the top of the printed circuit board and having a motor shaft coupling portion formed at the center thereof; and at least one or more screws adapted to be inserted into screw holes formed on the top peripheral portion of the housing and having screw heads formed thereon, the screw heads being engagedly coupled to the peripheral portion of the end cover and the end portions of the screws being brought into contact with the stator core.
