Modern Permanent Magnet Electric Machines Theory and Control

Modern Permanent Magnet Electric Machines Theory and Control

The late 1980s saw the beginning of the PM brushless machine era with the invention of high-energy density permanent magnets (PM) and the development of power electronics. Although induction motors are now the most popular electric motors the impact of PM brushless machines on electromechanical drives is significant. Today PM machines come second to induction machines. Replacement of electromagnetic field excitation systems by PMs brings the following benefits: No electrical energy is absorbed by the field excitation system and thus there are no excitation losses causing substantial increase in efficiency Higher power density (kW/kg) and/or torque density (Nm/kg) than electromagnetic excitation Better dynamic performance than motors with electromagnetic excitation (higher magnetic flux density in the air gap) Simplification of construction and maintenance Less expensive for some types of machines Modern Permanent Magnet Electric Machines: Theory and Control serves as a textbook for undergraduate power engineering students who want to supplement and expand their knowledge in the fundamentals of magnetism soft magnetic materials permanent magnets (PMs) calculation of magnetic circuits with PMs modern PM brushed DC machines and their controls modern PM brushless DC motors and drive control and modern PM generators. The book can help students learn more about electrical machines and can serve as a prescribed text for teaching elective undergraduate courses such as modern permanent magnet electrical machines. Since the book is written in a simple scientific language and without redundant mathematics it can also be used by practicing engineers and managers employed in electrical machinery or electromagnetic device industries. | Modern Permanent Magnet Electric Machines Theory and Control

Modern Management and Leadership Best Practice Essentials with CISO/CSO Applications

Modern Management and Leadership Best Practice Essentials with CISO/CSO Applications

In one modest-sized volume this book offers three valuable sets of knowledge. First it provides best practice guidance on virtually every large-scale task a modern manager may be involved in—from recruiting and hiring to onboarding and leading teams and from employee engagement and retention to performance management and working with difficult employees. Second it explains the essential concepts and practice of a range of effective leadership styles—including (but not limited to) servant leadership crisis leadership change agent leadership and diversity and inclusion leadership. Third it offers brief case studies from select CISOs and CSOs on how these management and leadership principles and practices play out in real-life workplace situations. The best practice essentials provided throughout this volume will empower aspiring leaders and also enable experienced managers to take their leadership to the next level. Many if not most CISOs and other leaders have had very little if any formal training in management and leadership. The select few that have such training usually obtained it through academic courses that take a theoretical broad brush approach. In contrast this book provides much actionable guidance in the nitty-gritty tasks that managers must do every day. Lack of management practical knowledge puts CISOs and CSOs at a disadvantage vis-a-vis other executives in the C-suite. They risk being pigeonholed as “security cops” rather than respected business leaders. Many articles on these subjects published in the press are too incomplete and filled with bad information. And combing through the few high-quality sources that are out there such as Harvard Business Publishing can take hundreds of dollars in magazine subscription and book purchase fees and weeks or months of reading time. This book puts all the essential information into your hands through a series of concise chapters authored by an award-winning writer. | Modern Management and Leadership Best Practice Essentials with CISO/CSO Applications

Wind Energy Systems: Solutions for Power Quality and Stabilization clearly explains how to solve stability and power quality issues of wind generator systems. Covering fundamental concepts of wind energy conversion systems the book discusses several means to enhance the transient stability of wind generator systems. It also explains the methodologies for minimizing fluctuations of power frequency and voltage. Topics covered include: An overview of wind energy and wind energy conversion systems Fundamentals of electric machines and power electronics Types of wind generator systems Challenges in integrating wind power into electricity grids Solutions for power quality problems Methods for improving transient stability during network faults Methods for minimizing power fluctuations of variable-speed wind generator systems This accessible book helps researchers and engineers understand the relative effectiveness of each method and select a suitable tool for wind generator stabilization. It also offers students an introduction to wind energy conversion systems providing insights into important grid integration and stability issues. | Wind Energy Systems Solutions for Power Quality and Stabilization

Preparing NEPA Environmental Assessments A User’s Guide to Best Professional Practices

Preparing NEPA Environmental Assessments A User’s Guide to Best Professional Practices

Although upwards of 50 000 environmental assessments (EAs) are prepared annually—compared to some 500 environmental impact statements (EISs)—the focus of U. S. National Environmental Policy Act (NEPA) regulations is on defining requirements for preparing EISs. Written by Charles Eccleston and J. Peyton Doub who have established themselves among the top environmental experts in the world Preparing NEPA Environmental Assessments: A User’s Guide to Best Professional Practices fills the need for an authoritative and comprehensive guide on how to prepare EAs. Bridging the regulatory gap this book identifies relevant EIS regulatory requirements that can be logically interpreted to also apply to EAs. It compiles and synthesizes information scattered throughout NEPA’s regulations executive orders and guidance documents and incorporates case law to provide additional clarification. The authors also draw on the professional experiences and best professional practices (BPP) of NEPA practitioners. From the fundamentals to more advanced topics the book presents a consistent methodology to help beginners students and professionals manage analyze and write legally sufficient EAs. It addresses dilemmas that have traditionally plagued preparation of EAs provides BPPs tools and approaches for resolving problems and introduces methods for streamlining the EA process. Building on Eccleston’s previous guide to EAs Effective Environmental Assessments: How to Manage and Prepare NEPA Assessments (2001) this book reflects the rapid changes in government policy over the past ten years. An indispensable source of practical information it provides readers with step-by-step direction and best practices for preparing defensible EAs. | Preparing NEPA Environmental Assessments A User’s Guide to Best Professional Practices
