Air motors: they're a gas!

27/06/2012

Dagmar Dubbelde offers four examples that demonstrate the versatility of air motors, from a device that turns waste process gas into useful electrical energy, to an ATEX-compliant brake motor at the heart of a system that empties toxic products from barrels.

Number-crunching FPGAs take the strain

These days, it’s easy to get the impression that variable speed drives are the best choice for controlling any motor in any application. But it’s not that easy, says Peter Schaffel, who explains how choosing the right motor starting technology is the key to optimising energy efficiency and to maximising plant life.

Squeezing the most from your drive

How best to puree fruit containing stones, or to separate fish from bones? And how to remove sinew and gristle from meat without waste? In the food industry, so-called soft separators are used to gently separate such materials, and these now rely increasingly on modern drive technology to ensure both economical running and consistently high product quality.
