    High voltage motor magnetic center and the Axial drift of the rotor

    In our plant there are electric motors of 6,6 KV, 2500 KW, 1480 rpm Always check the magnetic center prior to assembly and alignment. As is done with the motor without load, and the current in this case is 3 to 5% of the rated current, the magnetic centering forces are very weak. We have seen...
