The present invention relates to motor fixing brackets for reducing vibrations. The motor fixing brackets according to the present invention are fixed at the ends of a fixed axis and a rotary axis protruding at both sides of an out rotor type motor such that the out rotor type motor whose impeller is fixed at a rotary part is supported and fixed while the rotary part is positioned on an outer side of a fixed part within a casing whose both ends are open. The motor fixing brackets are bolt-fixed at both ends of the casing. At each of the fixing brackets, a coupling flange fixed on the circumference of a central axial coupling hub in a tripod shape, and an anti-vibration member is arranged within the axial coupling hub, respectively, to prevent vibration from being transferred to the casing via the coupling flange as the motor rotates. Therefore, the present invention prevents the vibration from being transferred to the casing surrounding the motor caused by the rotation of the motor by using the anti-vibration member installed at the rotational center of the motor, and also blocks shaking occurring via the vibration transferred to the casing or a big noise caused by a collision between the casing and the fixing bracket as in the conventional technique by basically blocking even the small sized vibrations occurring at the rotational center of the motor when the motor is driven. |
