In Frictional bearing ( Plain Bearing) supported High Tension Motors there is a possiblity to determine, set the centring of the rotor, which facilitates in Magnetic centring of the rotor at Running condition.
In case of Antifriction bearings supported HT Motors, Whether it is applicable ? If so How to determine the magnetic Centre of the rotor? whether it affects the life of the thrust bearing ( Normally Deep groove Brg) used in this application.
Question 2 ?
Whether a improperly centred rotor will induce high axial Vibration ?
Sources of axial vibration in motor ?
