Preface

Modern high-power electrical machines differ in the increased electromagnetic, mechanical, and thermal levels from those of former years. This book will provide progress in the development of heavy electric machine building and raise technical and economic indicators and competitiveness of machines. This is true not only of machines operating in networks of industrial frequency, but also of those in networks with nonlinear elements (in nonlinear networks), for example, with frequency converters. Practice makes great demands of professional knowledge from their creators, knowledge that should be useful at the modern level of the power industry. Profound academic knowledge only in any single engineering area, for example, in the field of heat transfer, will help an engineer only a little in his production activity. For the solution of a wide complex of problems, an engineer at work is required to have knowledge
