In this paper vibration of a high power induction electric motor of an air blower is estimated periodically monitoring both absolute vibration of housing-type bearings and relative vibrations of a rotor shaft. Insufficient IX dynamic stiffness of a rotor system is stated to be the main reason of high vibration amplitude of the IX frequency in an electric motor.[...].
