Motors and Drives
Motor and drive suppliers are rebounding from COVID-19, but are not out of the woods yet and are facing major supply chain issues and a semiconductor shortage.
The US Department of Energy (DOE) has issued rulemaking on test procedures for small electric motors for more than a decade.

While each has its place in HVAC applications, electronically commutated motors and variable frequency drives have important differences in simplicity, flexibility, cost and other factors
Size a variable-speed drive (VSD) for the application, and ask if a general-purpose drive will do or if more embedded intelligence is needed. Do you need a VSD, variable frequency drive (VFD) or adjustable speed drive (ASD)? (Trick question)
Programming variable frequency drives (VFDs) to fit most industrial applications require only the most basic settings to operate the motor. Understand these 5 VFD parameter changes to optimize VFD programming to fit most motor-drive applications.
A properly maintained variable frequency drive (VFD) can provide decades and cost-effective service. Making VFD inspections and maintenance part of facility oversight can improve outcomes.
