Patent ID: 7911089

Claim:
A fan motor for a refrigerator in which cool air is circulated by force, the fan motor comprising: a molding unit comprising: a stator having a shaft bearing unit mounting hole in the center thereof and core teeth which protrude radially outward so that a coil is wound thereon; and a circuit board having a circuit and a device which are electrically connected to the coil of the stator; wherein the stator and the circuit board having a terminal socket are integrally molded out of resin; and ends of the core teeth are exposed outwardly in the radial direction; and wherein a base is formed on one side of the stator; a shaft insertion hole connected to the shaft bearing unit mounting hole is formed in the center of the base; a side wall is formed protrusively from the edge of the base to surround the ends of the core teeth with a gap; and a terminal of the terminal socket is exposed outside the side wall; a shaft bearing unit inserted and fixed in the shaft bearing unit mounting hole; a rotor having a magnetic ring formed on the inner surface of a cup-shaped rotor housing, and a rotating shaft fixed at the bottom center of the rotor housing; wherein the side wall of the rotor housing is inserted in the gap between the side wall of the molding unit and the ends of the core teeth of the stator so that the magnetic ring is positioned opposite to the ends of the core teeth of the stator with a gap; and wherein the rotating shaft penetrates through the shaft insertion hole and thereby the rotor is supported by the shaft bearing unit; and an end cap whose edge is connected to the upper part of the side wall of the molding unit covering the rotor.
