Energy saving inverter drives for fan & pump applications

Quickly estimating the energy savings available by installing variable speed drives to motors is simple as their power consumption is governed by the cube law (see earlier article).   In the example given, a 10% speed reduction saves 27% of the running cost. Energy savings calculators are also available for more complex applications, but flow applications are particularly suited to this type of […]
