Auteur: Colin H Simmons Dennis E Maguire Neil Phelps Edition :Newnes pages:318Format :pdf language :EnglishThe Manual of Engineering Drawing has long been the recognised as a guide for practicing and student engineers to producing engineering drawings and annotated 3D models that comply with the latest British and ISO Standards of Technical Product Specifications and Documentation.This new edition has been updated to include the requirements of BS8888 2008 and the relevant ISO Standards, and is ideal for International readership; it includes a guide to the fundamental differences between the ISO and ASME Standards relating to Technical Product Specification and Documentation. Equally applicable to CAD and manual drawing it includes the latest development in 3D annotation and the specification of surface texture. The Duality Principle is introduced as this important concept is still very relevant in the new world of 3D Technical Product Specification.

Auteur: Austin Hughes Edition : Newnes pages:431Format :pdf language :EnglishElectric Motors and Drives is intended for non-specialist users of electric motors and drives, filling the gap between maths- and theory-based academic textbooks and the more prosaic 'handbooks', which provide useful detail but little opportunity for the development of real insight and understanding. The book explores all of the widely-used modern types of motor and drive, including conventional and brushless D.C., induction motors and servo drives, providing readers with the knowledge to select the right technology for a given job.
The third edition includes additional diagrams and worked examples throughout. New topics include digital interfacing and control of drives, direct torque control of induction motors and current-fed operation in DC drives. The material on brushless servomotors has also been expanded.
