Thank you ALL for the help. The units had me confused. I was referencing an old textbook and there answer was in steps/sec for the natural frequency.

I know that the square root of the torque stiffness divided by the Inertia equals the Frequency. I am trying to find the resonance.

What equation should I be using?

I agree it appears that I am off by a factor of 100, but I am not sure why. The equation I am using is: Square root of (360degrees*Holding Torque)/(step angle*Inertia)

I am trying to calculate the natural frequency of a stepper motor. Here is my work so far. The motor is rotated .3 degrees with a torque of .32 N*cm. Inertia = 48 g*cm^2 200 step/rev 1.8 degrees per step I am using the equation frequency = sqroot of (200*.32)/48 Which = 1.1547 steps/sec...
