We see from your search that you're looking for information on the term "Three-phase Motor",
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 Three-phase stepper is a smooth runner from
Astrosyn International Technology, which we summarised at the time by saying "Three-phase layout enables the stepper motor to provide very quiet, smooth motion as well as high accuracy, with a step angle of 1.2 degrees".
A few weeks before,
we featured the news release Relays tolerate industrial environments from
Crouzet: "Crouzet's new GN3 series three-phase and motor reversing solid-state relays suit a wide array of three-phase motor and heating applications".
In September 2007, we covered the news from OEM Automatic
concerning its Rosync KM65 motor
- take a look at Motor provides power boost
which says: "The Rosync KM65 motor is available with both single and three-phase winding".
Take a look also at the news release from Newton Tesla (Electric Drives), Micro-inverters cut the cost of variable speed,
as well as Screw compressors take dryers onboard from CompAir UK,
and Fan controller technologies and power consumption from Control Resources.
