Centrifugal stress of axial flow cooling fan for high speed compact electric motor is measured by the photoelastical stress frozen method, and also distribution of the bending stress of the fan blade is measured by the method of double layer. Nodes of the natural frequencies of the blade are compared with the distribution bending stress. And also residual stress of the torsional stress of the blade is measured by the method of stress annealing technology. The results of these experiments are centrifugal stress does not reach the limitation of the material allowance, natural frequencies of the fan blade will increase the bending stress, and residual stress is not so large to effect to the torsional area of the fan blade. These results are applicable to the data of designing for the rotating disk with slits.
