In this book a general matrix-based approach to modeling electrical machines is promulgated. The model uses instantaneous quantities for key variables and enables the user to easily take into account associations between rotating machines and static converters (such as in variable speed drives). General equations of electromechanical energy conversion are established early in the treatment of the topic and then applied to synchronous, induction and DC machines. The primary characteristics of these machines are established for steady state behavior as well as for variable speed scenarios. Important new applications for this technology (such as wind turbines, electric propulsion systems for large ships, etc.) are addressed and the book is illustrated with a large number of informative and detailed photographs, provided by various companies at the leading edge of research and applications in the field.

This book presents a Procedure for Calculating the Machine Parameters used in Stability Studies on AC Generators with Cylindrical Rotors. A sample exercise illustrates the Procedure for Calculating the Flux Densities, Reactance, Time Constants and a Method for Tracing the Machine Characteristic Curves, Saturation, Reactive Capabilities and Excitation "V" Curves. Also illustrated, is the Procedure for Calculating the Machine Design Characteristics on a Squirrel Cage Induction Motor. Specifically, the Tracing of the Performance Curves: 1. Efficiency, Power Factor and Line Current vs. Load 2. Acceleration Curves of Speed vs. Torque and Current 3. Thermal Limit Curves. Some Tabulated Values of Stator-Rotor Slot Combinations are also presented for avoiding excessive Magnetic Noise, harmful Torque Cusps, and stalled Sub-Speed Rotor Conditions.

Rotating electric machines are electric machines that are used to convert mechanical energy into electrical energy. There are three basic types of rotating electric machines, namely, the DC machine, the polyphase synchronous machine, and the polyphase induction machine. Steel, copper and aluminum are the three materials commonly used in manufacturing these machines. Rotating electric machines consists of two parts, the rotor and the stator. The rotor is the cylindrical rotating component whereas the stator is the annular stationary component. These components are made of a magnetic material, which conducts magnetic flux necessary for energy conversion process. In the case of synchronous and DC machines, the magnetic field is generated by field poles induced by the use of direct current. Rotating motors can be controlled by simple start/stop functions or may involve complex controls that regulate motor output parameters such as shaft speed and acceleration. This book includes some of the vital pieces of work being conducted across the world, on various topics related to the analysis, modeling and control of rotating electric machines. It aims to serve as a resource guide for students and experts alike and contribute to the growth of study on this subject.
