Some high-performance gearmotor systems can benefit from a more aggressive control approach that cranks up variable-frequency-drive operating frequencies. A whitepaper from SEW-Eurodrive shows how.
If you run your variable frequency drives at 60Hz and below, you are not alone. Nearly all the VFDs in North America operate below this nominal frequency threshold. Yet a growing number of high-performance gearmotor systems will benefit from a more aggressive control approach that cranks VFD operating frequencies up to 80, 90 or even 120Hz. The benefits can be significant, but getting there requires some extra design attention.
A whitepaper from SEW-Eurodrive called “Maximizing Gearmotor Speed Range” explains why it can be a good idea to push gearmotors beyond 60Hz. It covers how to select the proper gearmotor for a wide speed range and describes a technique called “supercharging” for taking existing gearmotor performance to a new level.
