Choosing the right motor and VFD type depends on a variety of factors, however, it is necessary to first look at how the characteristics of a motor change when the speed is reduced —Sponsored article ...

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 ...

This shift has created two common categories in residential cooling systems: smart ACs and normal ACs. Both use the same refrigeration technology to cool a room, yet the way users control and monitor ...

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 ...

This document discusses the operation of the MAX6650 and MAX6651, two fan controllers with linear closed-loop fan speed control. Temperature-based fan control is a necessity in a growing number of ...

Speed, torque, and horsepower are three inter-related parameters in motor control. The speed of a motor, measured in revolutions per minute (rpm), defines a motor's ability to spin at a rate per unit ...

Proper selection of component fans used in HVAC equipment continues to be a primary consideration in strategies to increase cooling efficiencies in data centers. Newer fan technology and pending fan ...
