Ask any engineer about electric motors and most of us visualise low- or medium-voltage three-phase equipment, either precision synchronous motors, driving machines or, more likely, standard asynchronous induction motors running pumps, fans and sometimes compressors. We see them everywhere, on all manner of industrial and utility plant, as well as heating and ventilating systems.
In the driving seat
Motors, drives and controls have been advancing fast, with a goal of improving plant operations, energy efficiency and the bottom line. Steed Webzell explores new systems, emerging best practice and top tips
Motor Madness
Man enough, simple and lowest cost have been the rules of thumb for specifying electric motors on plant. Brian Tinham explains how the guidelines are changing
