The book reflects the technical and production experience of foreign electric machine-building companies. It quite fully sets out the initial data for the design of electrical machines, provides detailed characteristics of electrical materials, considers the design of various types of electrical machines and their most important components and parts. Mechanical problems arising during the design are described, issues of vibration-free operation, balancing, calculation of bearings of electrical machines, etc. are considered. The book contains extensive reference material and examples of calculations. The book is designed for design engineers, calculators and operators of electrical machines, and can also be useful for university students specializing in the field of electrical engineering.
