For years, harmonic distortion was treated as a cost of doing business — something you managed with an external filter cabinet bolted on after the fact. A new analysis from Interact Analysis suggests that assumption is quietly expiring, and data centers are the reason. The demand signal According to Interact Analysis (Rising demand for low-harmonic […]
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 […]
from high vibration to high reliability with Clean Power VFD Reduction in vibrationacceleration Reduction in spike energy Motor and bearing failuressince the Clean Power VFDwas installed Objective Energir CCU had recurring bearing failures with thecurrent VFDs and wanted to eliminate the bearing and motor failures and reduce overall system stress. The objective was to find […]
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 […]
The Hidden Power in Your VFDs: Why Switching to Film Capacitors Could Save Your Operations Imagine this scenario: You’re the operations manager at a manufacturing plant. You’ve scheduled a routine shutdown for maintenance, and replacement of parts as preventive policy, such as replacing old Variable Frequency Drives (VFDs) by some you have held in stock […]
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 […]
