Abstract :
In this paper, the influence of the harmonic components of the electromagnetic force caused by manufacturing error on the electromagnetic vibration was examined. The influence of the electromagnetic force generated by manufacturing errors causes the rotor eccentricity and distorts the stator creating an imbalance excitation force triggering electromagnetic vibration. Furthermore we verified that the magnetic imbalance largely effects the electromagnetic vibration using the measured acceleration.
