Dynamatic drive clutches on induction motors have been installed 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.
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
