METHOD FOR ASSEMBLING ELECTRIC FAN

摘要

PROBLEM TO BE SOLVED: To provide a method for assembling an electric fan without the necessity that a weight having proper mass is added to a proper position so that the unbalance of a rotating member becomes less than a restricted value. SOLUTION: This method for assembling an electric fan including a fan 14 connected to the rotor 10 of an electric motor is equipped with a step determining directions of both unbalanced vectors A, B of the fan 14 and the rotor 10 and a step attaching the fan 14 and the rotor 10 so that the phases of both the unbalanced vectors A, B are mutually opposed.
