PROBLEM TO BE SOLVED: To provide a fan configuration element fixing angle determination method capable of reducing vibration of an entire fan unit and improving its general purpose.SOLUTION: This invention relates to a method for determining a fixing angle of fan configuration elements including motor shafts 2a, 2b and fans 3a, 3b and 3c in respect to an axis of a rotating shaft of a motor 1 at a fan unit F where at least one fan is connected to the motor shafts 2a, 2b of the motor 1 provided with motor shafts 2a, 2b. When the rotating shaft of the motor 1 is set as a Z-axis direction and a plane crossing at a right angle with this rotating shaft is set as an XY axis plane, the fixing angle of the fan configuration elements is determined in such a way that a sum of vectors of unbalance that is a displacement of center of gravity from an origin of XY axis at XY axis plane of the fan configuration elements may become minimum value.SELECTED DRAWING: Figure 1 |
