Are inverter-rated motors essential: Yes or No?
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 is a fairly unusual occurrence, but production engineers planning an upgrade to their facilities should be aware of the possibility. Here, Jerry Hodek, Managing Director of Rotor (UK) Limited explores the problem and looks at solutions and alternatives.
Global logistics and support for big power transmission projects
