This book was released on 2012-10-31 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a growing number of applications that require fast-rotating machines; motivation for this thesis comes from a project in which downsized spindles for micro-machining have been researched. The thesis focuses on analysis and design of high-speed PM machines and uses a practical design of a high-speed spindle drive as a test case. Phenomena, both mechanical and electromagnetic, that take precedence in high-speed permanent magnet machines are identified and systematized. The thesis identifies inherent speed limits of permanent magnet machines and correlates those limits with the basic parameters of the machines. The analytical expression of the limiting quantities does not only impose solid constraints on the machine design, but also creates the way for design optimization leading to the maximum mechanical and/or electromagnetic utilization of the machine. The models and electric-drive concepts developed in the thesis are evaluated in a practical setup.

Available in PDF, EPUB and Kindle. Book excerpt: NdFeB rare earth permanent magnets are more powerful and potentially much cheaper than any previous type. They have allowed improvements in PM machine capabilities including higher speed and power. Their physical properties are unusual and their effects on performance are neither clear nor understood.Combined heat and power (CHP) is the production of electricity as a by product of a heating plant. Gas turbine powered CHP units producing mains-quallty electricity more cheaply than the mains now seem feasible. There is a need for directly driven generators that run at > 50,000 rpm and produce power in the order of 50kW. This has been achieved by one of the REPM machines described in this thesis.The thesis examines magnets, NdFeB, and its physical properties (chapters 3 and 4). It then looks at a classical design procedure for FM machines using NdFeB (chapter 5) and at numerical methods (chapter 6). Two examples are examined last (chapters 7 and 8), namely a low speed machine and a 40 kW, 50,000 rpm generator. Problems included: NdFeB and its properties; balancing; mechanical stress; frequency and energy density; leakage and the equivalent circuit; magnetising the rotor; the magnet's operating temperature and life expectancy.The magnetic properties of NdFeB under compression were found to show no significant change. An inherently balanced design with high tolerances was used. Stress was reduced by using concentric cylinders of magnet, whilst electrical problems were dealt with using paralleled turns and a water jacket. The assembled rotor was successfumagnetised, which made the manufacture considerably easier. The operating temperature of the magnets was unpredictable because of the complex heat flow in the air gap but was acceptable. No irreversible fall in performance 'was evident, but the life expectancy is still uncertain. Thus the result was success: nearly 40kW at 50,000 rpm for several hours. The only limitation was the turbine's capacity!

Download or read book Speed Control of Interior Permanent Magnet Synchronous Machine written by Jigneshkumar Desai and published by GRIN Verlag. This book was released on 2022-09-27 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: Document from the year 2022 in the subject Engineering - General, grade: 12, , language: English, abstract: The creation of a simulation model for closed loop vector controlled IPMSM drive performance enhancement and speed control is described in this book. By regulating the torque component of the current, the model achieves superior speed tracking and rapid dynamic response under transient and steady-state circumstances. The control technique is used by both the proportional and integrated controllers in the PI controller. Combining two independent controllers and reducing the shortcomings of each results in a more effective controller. To offer optimal speed operation in the face of environmental changes, load variations, and structural disturbances, the Fuzzy Logic Controller for PMSM must be properly constructed. Using MATLAB Simulink, this book gives a comprehensive simulation of an internal permanent magnet synchronous motor driving system. Interior permanent magnet synchronous motors (IPMSMs) are used to improve machine performance and offer rapid torque response. IPMSMs are utilised in low and medium-power applications such as servos, robotics, variable-speed motors, electric vehicles, and computer peripherals. Because PM motor drives are becoming more popular, simulation systems capable of handling motor drive simulations are in great demand. Simulation tools can dynamically simulate motor drives in a visual environment, saving money and time and easing the development of new systems.

Download or read book Concepts in Turbocharging for Improved Efficiency and Emissions Reduction written by Mehrdad Zangeneh and published by SAE International. This book was released on 2014-09-22 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Legislative requirements to reduce CO2 emissions by 2020 have resulted in significant efforts by car manufacturers to explore various methods of pollution abatement. One of the most effective ways found so far is by shortening the cylinder stroke and downsizing the engine. This new engine then needs to be boosted, or turbocharged, to create the full and original load torque. Turbocharging has been and will continue to be a key component to the new technologies that will make a positive difference in the next-generation engines of years to come. Concepts in Turbocharging for Improved Efficiency and Emissions Reduction explores the many ways that turbocharging will deliver concrete results in meeting the new realities of sustainable, green transportation. This collection of very focused technical papers, selected by Mehrdad Zangeneh, PhD., a professor of thermo-fluids at University College in London, provides an assessment of several novel designs intended to improve fuel consumption and cap emissions, while maintaining torque at all speeds. The book is divided into four sections, each addressing the most cutting-edge technologies on the market today: o Two-Stage Turbocharging o Variable Geometry Compressors o Unconventional Compressor Configurations o Electrically Assisted Turbocharging
