Variable frequency drives have an Achilles Heel. Even though the VFD itself is protected against damaging electrical conditions, the drive's power cables can fail when subjected to heat or voltage ...

When an application requires changes in motor speeds to meet its objectives, a variable frequency drive (VFD) is often the first thing that comes to mind. This is for good reason—VFDs are typically ...

A Variable Frequency Drive (VFD) regulates the speed of a 3-phase AC electric motor by controlling the frequency and voltage of the power it delivers to the motor. These devices, also known as ...

During this webinar, attendees will learn how to reduce energy costs and unplanned downtime with intelligent HVAC variable frequency drives. Energy optimization algorithms that monitor real-time ...

This article presents a reference design for driving a vacuum fluorescent display (VFD) using the MAX15005 power-supply controller in a flyback topology. The design obtains multiple output voltages ...

To meet customer demand for greater output frequency range, Rockwell Automation expands the PowerFlex 6000T variable frequency drive range up to 120 Hz. The new output frequency range meets the needs ...

It's easy to understand how variable-speed motor drives benefit pumps and blowers from the energy curves that depict their performance. It is interesting to look at figures from the Energy Information ...

This is the second half of a two-part article discussing principles and application of the AC induction motors that provide motive power for most of the equipment HVACR engineers specify. In March, we ...
