- Samenvatting
John C Compter (M’76–PhD’84) received the M.Sc. E.E. degree from Delft University of Technology, Delft, The Netherlands in 1976, and the Ph.D. degree from Eindhoven University of Technology, Eindhoven, The Netherlands, in 1984. He joined the Philips Research Laboratories in1978 after military service. His involvement in projects, directed to electrical drives in equipment and products, was the basis for his dissertation, “Microprocessor controlled reluctance motor.” He was with Philips Domestic Appliances as Group Leader, Electrical Development, from 1984 till 1990. He then joined the Philips Centre for Industrial Technology (CFT), Eindhoven, The Netherlands, as Senior Consultant, Electrical Drives. In the period 1996-2008 he joined also Eindhoven University of Technology as an Adjunct Professor. His interests are in the areas of electromechanical drives and magnetic components for semiconductor production equipment, as e.g. a levitating and propelling planar motor for lithography, and for all kinds of domestic applications. His last position as senior scientist at Heidenhain in Eindhoven started in October 2008 and finished in February 2020.
He published as industrial researcher new ideas in about 50 publications and 50 patent families.
The added value of this book is that it combines the knowledge described in more than 100 scientific publications, the power of modern modeling tools, especially Mathematica, and the experience of designing linear motors and actuators for the high tech industry over more than 25 years.
