Abstract:
1. A brushless direct current (BLDC) motor for a hair dryer, comprising: a rotor housing comprising permanent magnets on an inner surface thereof and a shaft hole in a central portion thereof to receive a shaft; a sirocco fan coupled to an outer portion of the rotor housing and blowing air; a rotor frame having an inner circumference integrally coupled to an upper end of the shaft and an outer circumference coupled to the rotor housing; a stator core around which a coil is wound to interact with a magnetic field formed on the permanent magnets, thereby generating torque; a printed circuit board (PCB) coupled to a lower portion of the stator core by a screw (S); a base bracket including a support protrusion on an upper outer portion thereof to support the stator core; 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; a bolt coupling recess disposed on the support protrusion of the base bracket; and a bolt coupling hole passing through the bearing housing to correspond to the bolt coupling recess such that a bolt passes through the bolt coupling hole.
