Protecting VFDs From Overheating: An Easy Way to Calculate Cooling Requirements
Variable frequency drives are a hot topic. Advancements in VFD technology and reductions in price are driving rapid market adoption. Dramatic energy savings can deliver a payback period measured in months, and VFDs enable precise motor control in many industrial process applications. But VFDs are also hot in the literal sense: the advanced electronics pack more semiconductor components into a smaller form factor resulting in more intense heat generation. Elevated temperatures degrade performance, impair operational reliability and shorten service life.
