This paper discusses the bending vibration characteristics of a rotating shaft of a motor, with consideration of the electromagnetic sucking force which acts on a rotor, caused by the narrow electromagnetic field between a stator and the rotor. The dynamic response of the motor under the action of the whirling load of the shaft has been analyzed systematically by considering both the translational and rotary motions of the motor. In the analysis, the transfer matrix method is utilized to obtain the response of the shaft. The equation of longitudinal vibrations of a viscoelastic body is applied to the analysis of the viscoelastic foundation under the assumption of the structural damping. Numerical calculations have been carried out for the critical speeds and the response of both the shafts and the motor.
