Hello, everyone.<\/p>\n

I am attempting to calculate the natural frequency of the stator and frame of an electric motor to validate my analytical results using ANSYS Modal analysis. I have assumed that the four bolts on the motor frame act as fixed supports and have considered a maximum of 100 modes to determine the frequency range up to 10kHz in the analysis settings. After solving, I have inserted the deformation for each mode. Here, you can view the tabular data. I am concerned that the natural frequencies for each mode may be incorrect because I calculated the natural frequency for mode 1 to be about 500Hz. Is this the correct method for calculating the natural frequency of any structure in each mode?<\/p>\n
