How to diagnose bearing issues Bearings are key mechanical components of rotating machines and motors are obviously no exception. Bearing failures make a considerable portion of overall motor failures. In this post we look at factors influencing bearing lifetime, explore the failure modes and provide some hints how to assess Read more…
One reason for torsional vibration issue:Torque ripple In this post we look at torque ripple, its background, character and impact on the shaft string. After reading through you will have a brief idea what the torque ripple is and how to deal with it in a variable speed drive system. Read more…
Electro-mechanical interaction:Introduction Electric variable frequency drives provide lot of benefits in terms of energy savings, controllability and flexibility. But the VFD is just means to control the speed or torque of electric motors. The useful work is provided by the driven load such as e.g. pump, fan, compressor or mill. Read more…
