Rotating electrical machines - Part 14: Mechanical vibration of certain machines with shaft heights 56 mm and higher - Measurement, evaluation and limits of vibration severity
IEC 60034-14:2018 specifies the factory acceptance vibration test procedures and vibration limits for certain electrical machines under specified conditions, when uncoupled from any load or prime mover. It is applicable to DC and three-phase AC machines, with shaft heights 56 mm and higher and a rated output up to 50 MW, at operational speeds from 120 min?1 up to and including 15 000 min?1. This new edition includes the following significant technical changes with respect to the previous edition:- Improved explanation of the definition ?free suspension?.- Addition of an alternative method of rigid mount- Definition of an improved option for shaft key.
