Many mechanical drive trains, both fixed-speed and variable-speed, experience vibration. As operating speeds and controller performance continue to increase and motor mass and inertia fall, the danger of resonance problems increases. This subject area is complex and this description will be limited to an overview of the principles and identification of the key sources of excitation of mechanical resonances.
