Pendant des années, la distorsion harmonique a été perçue comme un coût inévitable — un problème que l’on gérait avec une armoire de filtres externe ajoutée après coup. Une nouvelle analyse d’Interact Analysis laisse croire que ce postulat est en train de disparaître discrètement, et les centres de données en sont la raison. Le signal […]
Why SCCR Cannot Be Reduced to a Breaker Rating Short Circuit Current Rating is often treated like a label to check and move on. That is a mistake. One of the biggest sources of confusion in the field is failing to separate two very different ideas: the ability to interrupt and the ability to withstand. […]
Using a 40HP 600V Fan or Centrifugal Pump Application Switching a 40HP, 600V fan from a Direct-On-Line (DOL) starter to a Variable Sine Wave Drive (VFS – the latest advancement in VFD Technology): Running at 55Hz instead of 60Hz typically produces substantial cost savings on the monthly electrical charges due to the affinity law for […]

Think about the last time you updated an app on your phone. Maybe it was your banking app, or your favorite navigation tool. You tapped « update, » waited a few seconds, and boom—new features appeared. But here’s the thing: your phone didn’t explode. Your bank account didn’t vanish. Everything just… worked. Now imagine if updating that […]
The Long Cable Run Dilemma: Where Should You Install the VFD? Sophia, a dedicated electrical engineer in a large industrial complex, has been tasked with installing a drive system where the motor is located hundreds of meters away from the control room. Like many engineers before her, she considers the usual question: Should I place […]
La puissance cachée de vos variateurs de vitesse : Pourquoi le passage aux condensateurs à film pourrait sauver vos opérations Imaginez le scénario suivant : Vous êtes le directeur des opérations d’une usine de fabrication. Vous avez programmé un arrêt de routine pour la maintenance et le remplacement de pièces à titre préventif, comme le […]
Understanding Motor Power Rating and VFD Ratings: The Reality Behind Normal Duty and Heavy Duty Selections When it comes to selecting a VFD for a motor, many professionals start with the values provided for Normal Duty (ND) and Heavy Duty (HD). It seems straightforward — these ratings supposedly help match a drive to a motor […]
Join our webinar: Stop VFD Cruelty Against Motors Imagine a world where variable frequency drives (VFDs) come with zero drawbacks. It might sound more visionary than a consultant’s day off, but stick with us—it’s real, and we’re excited to share it with you! If you’ve ever dealt with the consequences of premature system failure, you […]
A business owner phoned the office a few weeks ago asking if SmartD carried a 5 HP 380V Variable Frequency Drive with 380V input and output and discussed the pitfalls of motor failure. SmartD has a 5 HP standard 6 pulse open PCB modules available, and 20-30HP, 480V Clean Power Variable Frequency Drive that just […]
