Book Synopsis Modern Permanent Magnet Electric Machines by : Jacek F. Gieras
Download or read book Modern Permanent Magnet Electric Machines written by Jacek F. Gieras and published by CRC Press. This book was released on 2022-12-05 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Energy Efficiency in Electric Devices, Machines and Drives by : Gorazd Štumberger
Download or read book Energy Efficiency in Electric Devices, Machines and Drives written by Gorazd Štumberger and published by MDPI. This book was released on 2020-06-18 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Special Issue deals with improvements in the energy efficiency of electric devices, machines, and drives, which are achieved through improvements in the design, modelling, control, and operation of the system. Properly sized and placed coils of a welding transformer can reduce the required iron core size and improve the efficiency of the welding system operation. New structures of the single-phase field excited flux switching machine improve its performance in terms of torque, while having higher back-EMF and unbalanced electromagnetic forces. A properly designed rotor notch reduces the torque ripple and cogging torque of interior permanent magnet motors for the drive platform of electric vehicles, resulting in lower vibrations and noise. In the field of modelling, the torque estimation of a Halbach array surface permanent magnet motor with a non-overlapping winding layout was improved by introducing an analytical two-dimensional subdomain model. A general method for determining the magnetically nonlinear two-axis dynamic models of rotary and linear synchronous reluctance machines and synchronous permanent magnet machines is introduced that considers the effects of slotting, mutual interaction between the slots and permanent magnets, saturation, cross saturation, and end effects. Advanced modern control solutions, such as neural network-based model reference adaptive control, fuzzy control, senseless control, torque/speed tracking control derived from the 3D non-holonomic integrator, including drift terms, maximum torque per ampere, and maximum efficiency characteristics, are applied to improve drive performance and overall system operation.

Book Synopsis Practical Magnetic and Electromechanical Design by : Mark Juds
Download or read book Practical Magnetic and Electromechanical Design written by Mark Juds and published by Bookbaby. This book was released on 2020-10-22 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is written for students and practicing engineers involved in the design of magnetic and electromechanical devices. The material presented is a compilation of the practical approaches used over the author''s 37-year career at Eaton Research Labs and is intended to help the reader gain a "feel" for locations and strengths of magnetic fields and an intuitive insight into what magnetic fields do and how to use them. This book makes magnetics easy to understand and practical to apply in magnetic research, experimentation, and analysis of magnetic fields encountered in engineering challenges. Accurate and reliable methods are presented for the design of magnetic sensors, actuators, controls, and other electromechanical devices with the notable exclusion of rotating machines that are well covered by various authors and courses in university Electrical Engineering departments. Actuators, solenoids, and magnetic sensors have been around in various forms for over a century, and they are critical components of control and protection systems including relays and circuit breakers. This book has a strong foundation in the methods developed by H. C. Roters with additional topics in the areas of permanent magnet materials and permanent magnet performance in particular. The methodologies also take full advantage of complex spreadsheet capabilities, as well as finite element analysis as a counterpart to the calculations. Design examples include calculations for losses and temperature rise, which are critical for all electromagnetic systems. The smallest design usually has the highest temperature rise. The best design usually considers the trade-off between size and temperature rise. The design calculations presented are practical in the sense that they can be quickly and accurately applied in a spreadsheet model using the permeance method (also known as reluctance method or magnetic circuit method). The permeance method evaluates the magnetic field from the perspective of a magnetic circuit, analogous to an electric circuit. Chapter 1 describes this in detail and aims to provide an understanding of magnetic flux paths based on the simple question, "If I were a magnetic flux line, where would I go?" The accuracy of the permeance method is demonstrated with comparisons to measurements and finite element simulations. Practical methods also address the issues of time and effort. Some ideas need only "feasibility" level accuracy, while other design-specific challenges require high-level accuracy. This relates directly to budget and schedule issues on engineering projects. Increased effort (model detail, complexity, size, time) is needed to achieve increased accuracy. The best strategic approach is to use a method that is quick and provides enough accuracy to make a valid design decision. A spectrum of calculation methods can be considered 1) a hand calculation, 2) a simple spreadsheet model, 3) a complex spreadsheet model, 4) a 2D or axisymmetric finite element model, 5) a 3D finite element model. A spreadsheet model can also be used to quickly determine the starting size for a finite element model. A critical step for gaining confidence in the validity of any analysis is to check the results against those of a simple calculation. In general, when doing a complex analysis (such as a finite element simulation), the first step should be a simple calculation (such as a spreadsheet calculation) and a visualization of the magnetic field. The finite element simulation results can then be quickly reviewed for the shape of the magnetic field and the magnitude of the flux density, current and force, to judge if the results are reasonable. Finite element models have many input values and boundary conditions that are prone to typographical errors (such as a decimal point error, or a dimensional units error). Errors can be quickly detected when compared to a simple calculation and magnetic field visualization.
