We see from your search that you're looking for information on the term "Variable Frequency Drives",
and we have a large number of manufacturers' news releases and technical articles here on Engineeringtalk which will be of interest.
Let me be your guide.
Start with
the news release Guide compares drives and soft starters from
Danfoss Drives, which we summarised at the time by saying "Comprehensive and fully illustrated guide features variable frequency drives and soft starters for industrial applications".
Several months prior to that,
we featured the news release Master network added to drives from
WEG Electric Motors (UK): "WEG's PLC-2 card equips the CFW-09 drives for general digital control tasks, and for advanced positioning and synchronisation applications".
In May 2007, we covered the news from Danfoss Drives
concerning its Danfoss Drives' VLT AutomationDrive
- take a look at Variable frequency drive range extended
which says: "A modular design allows the VLT AutomationDrive to handle every motor control requirement from a single product platform".
Take a look also at the news release from SKF UK, Bearings need protection from electric currents,
as well as Machinery health transmitter has easy interface from Emerson Process Management,
and VLT AutomationDrive Available In 40 HP to 60 HP from Danfoss Drives.
