Electric Motor Analysis: Stator Problems

unique set of vibrations that can be detected.

Sources of Vibration in Electric Motors

Twice the line frequency (100 Hz or 120 Hz) is always a measurable vibration component in an electric motor. The magnetic attraction between the stator and rotor varies at this rate, and the iron itself changes dimension a little in the presence of the varying magnetic field due to "magnetostriction"*.
