We see from your search that you're looking for information on the term "Three-phase Supply",
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 Drives suit compressed air systems from
Lenze, which we summarised at the time by saying "The IceTech range of blasting equipment employs a high-pressure pump powered by a single three-phase 230V 50Hz motor to propel the dry ice pellets into a compressed air stream".
A few weeks before,
we featured the news release Drives and servomotors chosen for printing machine from
Lenze-ACTech: "Pringint of corrugated board requires both fast dynamic response and high precision from the servo equipment".
In March 2007, we covered the news from Moeller Electric
concerning its DIL M low-voltage vacuum contactors
- take a look at Vacuum contactors offer AC3 ratings
which says: "The DIL M vacuum contactor range now includes products with AC3 ratings from 580A to 1,600A, and is an ideal choice for controlling large motors".
Take a look also at the news release from Block UK, Three-phase supply is cost-effective option,
as well as TIG welder runs from single-phase supplies from Beta Century (UK),
and Drives optimise food process pumping efficiency from Lenze-ACTech.
