We see from your search that you're looking for information on the term "Variable Speed Drive",
and we have a large number of manufacturers' news releases and technical articles here on Manufacturingtalk which will be of interest.
Let me be your guide.
Start with
the news release Drive interface is internationally standardised from
Profibus Group, which we summarised at the time by saying "The established PROFIdrive profile for PROFIBUS and PROFINET became an internationally standardized drive interface, following publication of the IEC series 61800-7".
Earlier in the week,
we featured the news release AC drives simplify production line maintenance from
Control Techniques: "To simplify maintenance, an automotive production plant has restricted itself to one make and one type of frequency converter for all applications over 1.1kW, to eliminate long down-times".
In January 2008, we covered the news from Block UK
concerning its Harmonic filter modules
- take a look at Reduce harmonics in the power supply, save costs:
which says: "Companies can eliminate equipment failures and cut production downtime, repair and replacement costs by reducing the effects of harmonic distortion from power supply lines, says Bob Liddle".
Take a look also at the news release from Mitsubishi Electric Automation Systems, Regulation Part L, favours variable speed drives,
as well as Drives service programme to prevent downtime from ABB Automation Tech (Drives and Motors),
and Variable speed drives in southern England from ABB Automation Tech (Drives and Motors).
