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 ...

The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...

AC induction motors are widely used in industrial applications due to their reliability and low maintenance needs. Comprised of a stator and rotor, these motors convert electrical energy into ...

VFDs are used to control the speed and torque of AC motors so users can optimize system performance by running equipment at just the speed required to meet the demand of the load. Furthermore, VFDs ...

In today’s world, motors are ubiquitous, powering everything from household appliances to industrial machinery. The importance of optimizing motor control for energy efficiency cannot be overstated, ...

There are well-known benefits of using variable-frequency drives (VFDs) to reduce energy consumed by induction motors. Federal, state and local agencies in the U.S. now all give incentives for ...

What does a simple cascaded conveyor system look like? How to integrate a conveyor system using only the digital capabilities of modern variable frequency drives (VFDs). Simplifying the automation ...

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 ...

Matching drive to motor is essential to gain the best combination of torque, speed, and efficiency. Selecting the right drive is essential to getting the best performance and efficiency from an ...
