Variable frequency drives are now ubiquitous in the motor control industry, with dozens of large to small-scale players offering ready-built products. With just a few quick Google searches you can find drives to meet almost any need. However, like the proverbial square peg in a round hole, sometimes an off-the-shelf drive just doesn’t fit the use case.
To help motor control engineers determine when developing a custom VFD makes sense we have created a Custom VFD Checklist that outlines the considerations we work through when consulting with our clients. While we specialize in building custom AC motor drives, going the custom route is not our first choice if it can satisfactorily avoided.
