Title:
ヘアドライヤー用ＢＬＤＣモータ
Document Type and Number:
Japanese Patent JP5684833
Kind Code:
B2
Abstract:
Provided is a BLDC motor for a hair dryer, which includes high strength plastic parts integrated through injection molding. Thus, the number of parts is decreased to thereby decrease manufacturing costs and the weight of the BLDC motor. Furthermore, a sirocco fan installed in the BLDC motor is directly coupled to an outer circumferential surface of a rotor housing so as to optimize an assembling structure of the sirocco fan, thereby stabilizing the rotation thereof. Accordingly, vibration and noise due to rotation can be reduced, and an amount of introduced air can be maximized. To this end, the BLDC motor includes a rotor housing including permanent magnets on an inner surface thereof, and a shaft hole in a central portion thereof to receive a shaft, wherein a sirocco fan for blowing air is coupled to an outer portion of the rotor housing, a rotor frame coupling the shaft to the rotor housing to integrally rotate them, a stator core around which a coil is wound to interact with a magnetic field formed on the permanent magnets, thereby generating torque, a PCB coupled to a lower portion of the stator core by a screw, a base bracket including a support protrusion on an upper outer portion thereof to support the stator core, and a bearing housing coupled to an upper portion of the base bracket to support a ball bearing, and including a removal prevention protrusion in a lower outer portion thereof to prevent removal of the stator core.
