With the next phase of regulations coming into effect in January 2015, motors with a rated output of 7.5-375kW shall not be less efficient than the IE3 or will meet the IE2 efficiency and be equipped with a variable speed drive (VSD). With this in mind, fluid-flow application engineers are reviewing different technologies available to improve efficiencies further, says Siegfried Kreutzfeld, managing director at WEG Motors

There are documented cases of motors that have given 20 or 30 years’ sterling service only to fail within hours of being fitted with a variable speed drive which was meant to save energy and protect the motor from high load on start-up. It’s a fairly unusual occurrence, but production engineers planning an upgrade to their facilities should be aware of the possibility. Here, Jerry Hodek, MD of Rotor (UK) explores the problem and looks at solutions and alternatives.
