FAN STRUCTURE FOR A BLOWER MOTOR WITH A ROTOR YOKE INTEGRATED WITH A ROTARY SHAFT, CAPABLE OF MINIMIZING THE VIBRATION AND NOISE IN THE OPERATION OF THE BLOWER MOTOR

摘要

PURPOSE: A fan structure for a blower motor with a rotor yoke integrated with a rotary shaft is provided to simplify an assembling process of the blower motor and to minimize vibration and noise caused by the same in the operation of the blower motor.;CONSTITUTION: A fan structure for a blower motor with a rotor yoke(200) integrated with a rotary shaft(300) includes a fan(100). The fan includes; a plurality of blades(110) which are arranged along a circumferential direction; a circular edge portion which connects the upper parts of the blades; a receiving unit which is arranged in the inner center of the blades in order to form an air current space between the blades and the receiving unit; and a connection unit of a flat plate shape which connects the lower parts of the blades and the lower part of the receiving unit. The rotor yoke is fixed inside the receiving unit. The rotary shaft is penetrated through the center of the internal space of the rotor yoke and extended to the lower part of the receiving unit, thereby becoming protruded.;COPYRIGHT KIPO 2013
