Experience the benefits of variable speed pumping without the headaches of variable frequency drives

Dynamatic drive clutches, “the cure for VFD headaches,” have been installed on induction motors in wastewater treatment applications for many decades, primarily due to the inherent durability, simplicity, and reliability of Eddy Current technology. Even though variable frequency drives (VFDs) gained popularity in the 1980s, they can can come with their fair share of issues and headaches.

Eddy Current Drives (ECDs) “the cure for VFD headaches” offer the following benefits:

  • No additional conditioning/cooling needed – capable of continuous operation in 40° C ambient temperature

  • No harmonic mitigation needed

  • Reduced multiple, medium voltage motor starting/stopping

  • Unaffected by power quality fluctuations that can trip or destroy VFDs

  • Lower cost installation and commissioning due to less complex systems

  • Simple to use digital control integration

  • Minimal space requirements – electronics are 60-70% smaller than comparable medium voltage VFDs

  • Less downtime – proven rugged and reliable electromagnetic clutch design

  • Outlast VFDs by as much as 6:1

  • Easy to maintain by on-site staff using low-cost parts
