Summary:

Electric Drives and Electromechanical Devices: Applications and Control, Second Edition, presents a unified approach to the design and application of modern drive system. It explores problems involved in assembling complete, modern electric drive systems involving mechanical, electrical, and electronic elements. This book provides a global overview of design, specification applications, important design information, and methodologies.This new edition has been restructured to present a seamless, logical discussion on a wide range of topical problems relating to the design and specification of the complete motor-drive system. It is organised to establish immediate solutions to specific application problem. Subsidiary issues that have a considerable impact on the overall performance and reliability, including environmental protection and costs, energy efficiency, and cyber security, are also considered.- Presents a comprehensive consideration of electromechanical systems with insights into the complete drive system, including required sensors and mechanical components- Features in-depth discussion of control schemes, particularly focusing on practical operation- Includes extensive references to modern application domains and real-world case studies, such as electric vehicles- Considers the cyber aspects of drives, including networking and security
