LAMINATION STEELS Third Edition - a CD-ROM: a compendium of lamination steel alloys commonly used in electric motors was published March 1, 2007. It includes:
- magnetic information from 13 international producers
- a PDF document with over 1,700 pages of up-to-date material performance charts, product information and data values for both the Core Loss and Magnetization properties for a wide variety of lamination alloys
- magnetization values in Oersteds and amperes/meter and core loss values in both watts/pound and watts/kilogram for all materials included in the CD-ROM, including commonly used lamination steel alloys as well as amorphous and powdered core materials
- more than 180 spreadsheets with detailed magnetic property data for all the materials covered in the PDF document, allowing for easy insertion of this information into motor simulation and magnetic analysis software

Uday Deshpande, formerly Technology Manager, Black & Decker directs the group in establishing tasks and completion dates, watched by Bob Stewart and Dr. Prag Pillay who is directing the research at Clarkson University.
The research is being conducted at Clarkson University, Potsdam, New York, under the guidance of Dr. Pragassen Pillay, Clarkson's Jean Newell Distinguished Professor of Electrical and Computer Engineering.
Clarkson University Electrical and Computer Engineering Professor Pragasen Pillay and research assistants M.S. Luke Dosiek (left) and Ph.D. student Lotten Mthombeni (right) use specialized equipment to measure losses in motor lamination steel.
Participating in, and financially supporting the work to date, are SMMA member companies Advanced Motors and Drives, Black & Decker, Eaton Corp., Lamination Specialties, Magnetic Instrumentation/KJS, and Proto Laminations Inc.
