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 ...

Using variable frequency drives (VFDs) to control the speed of a compressor can provide improved occupant comfort and quieter operation in air conditioning and heat pump applications. Tight ...

Many of us will have experimented with brushless motors, and some of us will have built our own controllers rather than using an off-the-shelf part. Doing so is a good way to understand their ...

The Pfix M4288 Series variable-frequency drive (VFD) controller is a self-contained field-mountable pump and drive controller designed as a supplement or alternative to PLC-based drive and pump ...

A typical low-voltage variable-frequency drive. Industrial facilities commonly use variable-frequency drives (VFDs) to control the speed at which alternating current motors operate. Let’s examine a ...

The VACON 100 FLOW is an AC drive specifically designed to improve flow control for multi-pump applications in which several pumps are used in place of a single one. Multiple pump solutions are ...
