Adjustable speed drives (ASDs) or variable speed drives (VSDs), also called variable frequency drives (VFDs), typically control a motor's velocity or Adjustable speed drives (ASDs) or variable speed ...

Single- and three-phase alternating current (AC) motor speed can be controlled by controlling the frequency of the voltage coming to it. Motor speed has a lot to do with the capacity of refrigeration ...

Variable speed drives (VSDs), sometimes also known as variable frequency drives, are electronic devices used to regulate the speed of an ac induction motor. Electric motors consume approximately 25% ...

It is interesting to look at figures from the Energy Information Administration about where energy gets consumed in our economy. These figures reveal that industrial uses account for 31% of all energy ...

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 ...

Utility power plant generators are usually designed for a power factor (PF) of .8 to .9. If demand-side PF is lower than the designed PF, the generator current will rise above the equipment's rated ...

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 ...

Variable speed fans, on the other hand, use mechanical or electrical drive systems for control When a fan operates at constant speed with variable inlet vanes or parallel-bladed inlet box dampers, the ...

Yokogawa's unique 6-channel WT1800 precision power analyser with harmonic analysis enables you to gain a complete and accurate knowledge of the power and harmonic performance of your system. Buy a ...

THE USE OF INVERTER-BASED variable speed drives (VSDs) in home appliances is forecast to double over the next five years, according to the latest detailed THE USE OF INVERTER-BASED variable speed ...
