Variable speed starters bridge gap between motor starters and variable speed drives
Industrial Drives : 23 August, 2015
There’s no getting around the ErP directive for machine and system builders since the second stage of the EU motor efficiency regulations took effect at the start of this year. Until now the industry has mainly focused on electric motors, but that is not enough. To optimise the efficiency of machines and systems, the switchgear also has to be taken into account, argues Stuart Greenwood, Product Marketing Manager Industrial Control & Automation, Eaton UK.

Sanitaryware machine costs cut without sacrificing functionality or safety

Smart AC motor allows wide range of running speeds to be freely set
Industrial Drives : 19 November, 2013
The Lenze Smart Motor is not a variable speed drive but instead one that has the running speed freely set over a 5:1 speed range, from 500 to 2600 rev/min. This offers cost savings to machine builders, particularly in materials handling and conveyors, by reducing the number of variants of geared motors used. Instead of several drives with different gear ratios, a single model of Smart Motor can be used with different programmed speeds.
