Experienced product designers are increasingly expected to be adept at incorporating a range of components into their designs. Students and experimenters too need to look beyond basic circuits and devices to achieve adequate design solutions. For those experienced in engineering design, this is the guide to electric motors. This book will allow engineers and designers to marry the technologies they know about with motor technology, and hence to incorporate motors into their products. Of the many good books on motors, such as Electric Motors and Drives by Hughes, none offer the engineering professional a tailored guide to motors taking into account their expertise. This book fills that gap. Irving Gottlieb is a leading author of many books for practising engineers, technicians and students of electronic and electrical engineering. Practical approach with minimum theory Covers a core area ignored by many electronics texts Shows how to incorporate motors into electronic products

Gross and fine motor skills are a prerequisite for writing and without developing these skills effectively, learning how to write can be a near impossible task. This book is aimed at all those working within Early Years settings, who wish to develop children's motor skills. With the expansion of technology, the demands of busy lives and the increase in stranger danger, children's upbringing is very different today. Children are not experiencing the daily activities that help to develop core stability, balance and physical strength. As a teacher within the EYFS, Ruth noticed the increasing number of children entering her setting with physical developmental delay and has written this book to provide practitioners with some simple but effective activities to help develop gross motor skills.

Brushless permanent-magnet motors provide simple, low maintenance, and easily controlled mechanical power. Written by two leading experts on the subject, this book offers the most comprehensive guide to the design and performance of brushless permanent-magnetic motors ever written. Topics range from electrical and magnetic design to materials and control. Throughout, the authors stress both practical and theoretical aspects of the subject, and relate the material to modern software-based techniques for design and analysis. As new magnetic materials and digital power control techniques continue to widen the scope of the applicability of such motors, the need for an authoritative overview of the subject becomes ever more urgent. Design of Brushless Permanent-Magnet Motors fits the bill and will be read by students and researchers in electric and electronic engineering.

For this revision of their bestselling junior- and senior-level text, Guru & Hiziroglu have incorporated eleven years of cutting-edge developments in the field since Electric Machinery & Transformers was first published. Completely re-written, the new Second Edition also incorporates suggestions from students and instructors who have used the First Edition, making it the best text available for junior- and senior-level courses in electric machines. The new edition features a wealth of new and improved problems and examples, designed to complement the authors' overall goal of encouraging intuitive reasoning rather than rote memorization of material. Chapter 3, which presents the conversion of energy, now includes: analysis of magnetically coupled coils, induced emf in a coil rotating in a uniform magnetic field, induced emf in a coil rotating in a time-varying magnetic field, and the concept of the revolving field. All problems and examples have been rigorously tested using Mathcad.
