For many retrofit projects, the use of a VFD seems like a “no brainer.” Drives are now cheaper and more reliable than ever, and the benefits of efficient control of motors can’t be beat. Still, there ...

The decision to use either a soft starter or variable speed drive is a fairly common one. And it’s a decision that has become increasingly important with the advent of global energy efficiency ...

Speed optimization features also improve productivity, as do remote operator interfaces that link and coordinate multiple drives. What can designers do to ensure higher productivity from the ...

Variable speed drives (VSDs), sometimes also known as variable frequency drives, are electronic devices used to regulate the speed of an ac induction motor. Electric motors consume approximately 25% ...
