WebFeb 26, 2024 · The VFD (variable frequency drive) is a type of motor control that converts direct current (dc) into variable-frequency alternating current (ac). These VFD's not only convert the power, but also boost and regulate it before sending it to the ac motor. The VFD does this by varying the field on the stator and rotating its angle. WebMay 1, 1999 · The secret to troubleshooting VFDs is using SMARTS, an acronym for a proven method used in troubleshooting numerous VFD installations over the last 20 years. SMARTS stands for Safety, Manuals, Application, Readings, Talk, and Symptoms. This technique can be applied to all kinds of VFDs and other electrical equipment as well.
