Whether it s pumps, turbines, compres-sors, alternators, ships, rolling mills,paper mills, movers, fans or special ap-plications our MOTORS and generatorsare specifically designed to meet ourclient s particular needs. All of our MOTORS and generators aredesigned based on a flexible modularstructure developed using moderncomputer aided engineering methods. This permits our engineering staff toefficiently configure the right machinefor our Customer s origins of the Ansaldo name trace back over 150years when the company was founded as a respectedship builder in 1853.

2 Through diversification and expansion, Ansaldoestablished itself as one of the pioneers and foundersof Italian manufacturing, engineering and Sistemi Industriali (ASI) was born as a branchof Ansaldo that extended the group s expertise andbusiness in power electronics, MOTORS & generatorsand automation. Over the past century, ASI hasspecialized in providing innovative power controland system solutions that have satisfied hundreds ofcustomers strengths: Aluminum or Copper bar Rotor Micasystem VPI insulation system Custom tailored to meet your specific needsWe are specialistsin:High speed designs, stiff shaft designs, hazardous area machines including explosion proof enclosures, vertical machines up to 10,000 kW(13400 HP) and special Induction MachinesSeries CT/CR/CB/W/N/ET/CADS eries CTSeries CROur standard induction machines are built with analuminum squirrel cage rotor.

3 Rotor packs are madefrom single punch laminations up to size 1000. Largerpacks are made using lamination segments. End ringsare made of a special aluminum alloy which is weldedto the cage using state of the art techniques. Stators arebuilt as self contained units which are mounted into theframe after the coils have been inserted and the wholeunit has undergone our MICASYSTEM VPI Our Micasystem VPI insulation system is one of the beston the market.

Designed to meet specific applicationneeds on a job-by-job basis, our synchronous MOTORS provideoutstanding performance and reliability. These machines arethe preferred choice on large compressor and vertical pumpapplications.

5 They are also widely used for wind tunnel fans andcycloconverter applications. Ansaldo Sistemi Industriali also hasconsolidated experience in generators coupled to diesel enginesand turbines of all types. These generators are specifically designed with all the constructionfeatures to withstand the pulsating torque generated by a dieselengine to ensure smooth parallel operation. The constructionfeatures on our synchronous machines are basically the same asthose on our induction MOTORS for similar applications.

Wehave recently upgraded our testing capacity and canperform full system testing in back-to-back configurationup to 45 MW at nominal operating speed. With 5 teststands covering mq plus an additional mq ofexternal area for drives and transformers, we are nowable to extend our rigorous testing procedures to high-power machines - an additional guarantee there will beno surprises when the equipment goes out to the benches are independent which allows us toperform routine and type tests as well as full load testingup to 4 MW @ 1,500 r/min (1,200 r/min on Verticalmachines) on several machines at the same time, helpingto reduce lead times.
