#Energy efficiencyPart 3: Selection of VFD technology What type of VFD technology fits the best your demands? The answer depends mainly on your process and operation philosophy. Process dynamics Is your process very dynamic and fast response is required? Then you will need a high performance drive that can track Read more…
#Energy efficiency Part 2: Applications with energy saving potential What applications can benefit from variable frequency control the most? To help understand it we use some fundamental equations (don’t worry, there will be no high mathematics!). Mechanical power Pmech is the product of torque T and angular velocity w. The Read more…
Reliability and availability (Part 2: MTBF) Let’s start with the mystery around MTBF (Mean Time Between Failures). You may disagree with me, but please give me a chance and read to the end before you make your mind. Many people believe that the higher MTBF figure the more reliable system Read more…
Reliability and availability (Part 1: Introduction) Reliability and availability are crucial characteristics of drive systems and every downtime negatively impacts the productivity and profitability of a plant. In this series we would like to walk through the topic, provide some (theoretical) background and also a more practical approach. We have Read more…
#Energy efficiency Part 1: Introduction Energy efficiency is a big topic that the society talks about. One reason is the increased awareness of the impact of human on the planet and effort to minimize this impact, other reason is purely economical considering cost benefits due to energy savings and competitive Read more…
We go live! Welcome and thanks for visiting this site. We would like to bring some interesting articles from the world of variable frequency drives and drive systems as well as provide inspiration to think about. The idea is to put certain topics in a different perspective and eliminate some Read more…
