By analysing the amplitude of the shaft vibration, this article concludes that when the bolts get loose, it will result in resonance at the second criticalspeed and serious vibration.
On the data obtained from the measurement and analysis, the shaft's flexibility, one-sided magnetic pull and the criticalspeed of shaft of the electrical motor are computed.

With increasing shaftspeed of rotation, heat evolution and temperature rise become a critical problem.
