The way we control the speed of fan motors or pump motors has tremendously changed in the past two decades with the introduction of variable-frequency drives (VFDs), aka variable-frequency controllers ...

When implementing cooling solutions for electronic equipment, system designers are confronted with a complex set of variables. The cooling requirements are typically dynamic, and ambient temperatures ...

Many power plants regulate fan airflow with mechanical controls, such as dampers. In some applications using fixed-speed motors in combination with dampers may not be the most energy efficient option.

If your computer's running a little loud for your tastes, it's probably because your fans are running at full speed—even if they don't need to be. Here are a few ways to manage your fan's speed so ...

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 ...
