 pdf fileElectric Machines and Drives
Electric Machines and Drives, The subject of this book is an important and diverse field of electric machines and drives. The twelve chapters of the book written by renowned authors, both academics and practitioners, cover a large part of the field of electric machines and drives. Various types of electric machines, including three-phase and single-phase induction machines or doubly fed machines, are addressed. Most of the chapters focus on modern control methods of induction-machine drives, such as vector and direct torque control. Among others, the book addresses sensorless control techniques, modulation strategies, parameter identification, artificial intelligence, operation under harsh or failure conditions, and modelling of electric or magnetic quantities in electric machines. Several chapters give an insight into the problem of minimizing losses in electric machines and increasing the overall energy efficiency of electric drives.

 pdf fileinternal combustion engine efficiency
Power and efficiency limits for internal combustion engines via methods of finite-time thermodynamics, I. INTRODUCTION “In selecting an idealized process one is always faced with the fact that the simpler the assumptions, the easier the analysis, but the farther the result from reality” (Ref. 1, p. 23). The more assumptions we make, the farther we are likely to be from reality. On the other hand, detailed, realistic models for internal combustion engines are difficult and expensive to compute and analyze.2 If we are interested in maximum power output or in maximum efficiency of internal combustion engines two ways of approaching the problem are possible. We could incorporate the major loss terms such as friction loss, heat leak, and incomplete combustion in a simple model based on airstandard cycle with rate-dependent loss mechanisms. Then using optimal control theory we can compute the piston trajectory which yields maximum power output. This approach has been realized in Refs. 3 and 4 and it is an application of the methods of finite-time thermodynamics. Another approach is to use a more detailed, “realistic” model and try only to fmd approximate upper limits for possible performance rather than to determine directly the optimum trajectory which yields the best performance. This approach has been realized in Ref. 5 and it is also an application of the methods of finite-time thermodynamics.

 pdf fileMachine Management System Tools and A Life Cycle Cost Calculation
A Life Cycle Cost Calculation and Management System for Machine Tools, Abstract A life cycle cost calculation and management program for machine tools is presented here. Its aims are: to provide life cycle cost data prediction at the offer phase and to support design phase decisions by managing real machine tool behaviour data. The system is being tested in various types of machine tools such as machining centres, transfer lines and grinding machines. It comprises four main areas : cost model design, cost concept and basic data definition, product model design and instance cost calculation. It also allows for generating customer defined outputs in various formats and integration with commercial reliability analysis packages

 pdf fileConceptual Machine Design and Mechanical Design Handbook
Faster, better, and cheaper is the name of the game for machine and device designers. Demands for higher performance and increasingly efficient machines designed in a shorter amount of time with smaller design teams are challenging machine designers to improve their design processes. The Aberdeen Group identified these top machine design challenges after interviewing engineering managers and designers from 160 machine design companies in January 2008 (see Table 1). The study also discovered that to meet these challenges, successful companies follow the mechatronics design approach – they increase integration between mechanical, electrical, control, and embedded programming design processes. This machine design guide examines the best practices and tools that successful machine designers use to make different design trade-offs, meet design challenges, and increase profit.

 pdf fileHow Two stroke Engines Work
If you have read How Car Engines Work and How Diesel Engines Work, then you are familiar with the two types of engines found in nearly every car and truck on the road today. Both gasoline and diesel automotive engines are classified as four-stroke reciprocating internal-combustion engines. There is a third type of engine, known as a two-stroke engine, that is commonly found in lowerpower applications. Some of the devices that might have a two-stroke engine include: Lawn and garden equipment (chain saws, leaf blowers, trimmers) Dirt bikes Mopeds Jet skis Small outboard motors Radio-controlled model planes In this edition of HowStuffWorks, you'll learn all about the two-stroke engine: how it works, why it might be used and what makes it different from regular car and diesel engines. Two-stroke Basics
