Vibration problems which occur after some considerable period of operation are often solved by simply replacing or repairing worm system components. This may reduce the vibration to tolerable levels but does not eliminate the basic cause for the vibration having developed. The vibration usually recurs after the same or a shorter period of operation following each subsequent replacement/repair

Sep 22, 2011The speed of an induction motor can be easily controlled by varying the frequency of the 3-phase supply; however, to maintain a constant (rated) flux density, the applied voltage must also be changed in the same proportion as the frequency (as dictated by Faraday s law).This speed control method is known as Volts per Hz.
