Recent Developments of Electrical Devices is composed of the papers which were presented at the XVI International Conference on Electrical Machines - ICEM2004, which was held in Cracow, Poland on September 5-8, 2004. The contributions selected for the book cover a wide spectrum of theory and practice, thus they are deeply rooted in engineering problems, being simultaneously of high theoretical level. This way the contents of the book is believed to touch the heart of the matter in electrical drives (theory, control systems and applications). The book, stating the recent developments of electrical drives, can be useful for engineers and researchers investigating and designing electrical and electronic devices as well as for students and young researchers dealing with electrical and electronic engineering, computer sciences (advanced computer modelling, sophisticated control systems with artificial intelligence tools applied, optimal design bye use of classical and genetic algorithms employed), applied mathematics and all the topics where electromagnetic, thermal, mechanical phenomena occur. Recent Developments of Electrical Devices covers a wide range of interest of industry engineers, and scientists involved in modelling, control, measurements, new motor structures design, and could be also useful for engineers working in the field of electrical drives implementation.
