| Abstract: | A research is done of the modes of radial vibration of the aero AC electric machines stators.The reason behind the making up of the electromagnetic force is analyzed. The mode step of the vibration and noise caused by the radial electromagnetic force wave can be determined,and the volume can be detected in a measurement made to the harmonic wave in the magnet field.In a sampling test,analyzed are the level of the excited vibration wave of component force and the range of the frequency of the electromagnetic noise of aero AC dynamos. |
