White Paper: "Building a Reliable VFD System" from Belden

Aug. 18, 2009
This white paper examines the benefits of Variable Frequency Drives and special considerations that must be given to their design, installation and operation.

VFDs offer many benefits: principle among them the ability to save a substantial amount of energy during motor operation. In that sense, these devices represent both an attractive, “green” engineering solution, and an economical choice. Other benefits worth mentioning include the following: they can maintain torque at levels to match the needs of the load, improve process control, reduce mechanical stress on 3-phase induction motors by providing a “soft start,” and improve an electrical system’s power factor. What’s more, legacy systems that now use throttling devices to regulate motor speed can be retrofitted with VFDs to make speed regulation much more efficient and precise.
