Investigation, Analysis and Design of the Linear Brushless Doubly-Fed
AN ABSTRACT OF THE THESIS OF Farroh Seifkhani for the degree of Master of Science in Electrical and Computer Engineering presented on February 8, 1991 . Title: Investigation, Analysis and Design of the Linear Brush less Doubly-Fed Machine.Redacted for Privacy Abstract approved: K. Wallace This thesis covers theefforts of thedesign, analysis, characteristics, and construction of a Linear Brush less Doubly-Fed Machine (LBDFM), as well as the results of the investigations and comparison with its actual prototype. In recent years, attempts to develop new means of high-speed, efficient transportation have led to considerable world-wide interest in high-speed trains. This concern has generated interests in the linear induction motor which has been considered as one of the more appropriate propulsion systems for Super-High-Speed Trains (SHST). Research and experiments on linear induction motors arebeing actively pursued in a number of countries. Linear induction motors are generally applicable for the production of motion in a straight line, eliminating the need for gears and other mechanisms for conversion of rotational motion to linear motion. The idea of investigation and construction of the linear brushless doubly-fed motor was first propounded at Oregon State University, because of potential applications as Variable-Speed Transportation (VST) system. The perceived advantages of a LBDFM over other LIM's are significant reduction of cost and maintenance requirements. The cost of this machine itself is expected to be similar to that of a conventionalLIM. However, it is believed that the rating of the power converter required for control of the traveling magnetic wave in the air gap is a fraction of the machine rating. -

ELECTRICAL ENERGY UTLISATION Jacek F
ELECTRICAL ENERGY UTLISATION Jacek F. Gieras and Izabella A. Gieras Adam Marszalek Publishing House, Torun, 1998 This text evolved from notes used in teaching an undergraduate course Energy Utilisation at the University of Cape Town. As the curricula of electrical engineering programmes became more and more overcrowded, many electrical engineering departments decided to limit the number of compulsory courses in heavy current electrical engineering. As a result, the number of lectures in electrical machines and related subjects have been reduced. Under such circumstances students need a concise textbook which covers electrical motors with emphasis on their performance, selection and applications, characteristics of modern electrical drives including variable speed drives and the use of electrical energy in households. This textbook deals with fundamentals of electrical motors, drives, electrical traction and domestic use of electrical energy. It is intended to serve second or third year students taking a one-semester course in energy utilisation or electric power engineering. Transformers and electromechanical generators have been omitted as transformation and generation of electric power is usually covered by a parallel course in power systems. The textbook consists of seven chapters: 1. Energy and drives, 2. D.c. motors, 3. Three- phase induction motors, 4. Synchronous motors, 5. Variable-speed drives, 6. Electrical traction and 7. Domestic use of electrical energy. Chapter 7 also contains principles of illumination. For a one semester course and two lectures per week the authors recommend the first four chapters. For four lectures per week the authors recommend all seven chapters. Students using this textbook should have taken courses in circuit theory and electromagnetism as prerequisites. -

Three-Phase Induction Motor

BACKGROUND INFORMATION The three-phase squirrel-cage induction motor can, and many times does, have the same armature (stator) winding as the three-phase synchronous motor. As in the synchronous motor, applying three-phase currents to the armature creates a synchronously-rotating magnetic field. The induction motor rotor is a completely short-circuited conductive cage. Figures 1 and 2 illustrate the rotor construction. Revised: April 11, 2013 1 of 10 Three-Phase Induction Motor Figure 1: Induction machine construction. Figure 2: Squirrel-case rotor. Revised: April 11, 2013 2 of 10 Three-Phase Induction Motor The rotor receives its excitation by induction from the armature field. Hence, the induction machine is a doubly-excited machine in the same sense as the synchronous and DC machines. The basic principle of operation is described by Faraday’s Law. If we assume that the machine rotor is at a standstill and the armature is excited, then the armature-produced rotating field is moving with respect to the rotor. In fact, the relative speed between the rotating field and the rotor is synchronous speed. -

Journal of ELECTRICAL ENGINEERING, VOL. 62, NO. 5, 2011, 302{308 MODELING AND SIMULATING OF SINGLE SIDE SHORT STATOR LINEAR INDUCTION MOTOR WITH THE END EFFECT ∗ Hamed HAMZEHBAHMANI Linear induction motors are under development for a variety of demanding applications including high speed ground transportation and specific industrial applications. These applications require machines that can produce large forces, operate at high speeds, and can be controlled precisely to meet performance requirements.

Single Phase to Single Phase Step-Down Cycloconverter for Electric Traction Applications
American-Eurasian Journal of Scientific Research 11 (4): 271-274, 2016 ISSN 1818-6785 © IDOSI Publications, 2016 DOI: 10.5829/idosi.aejsr.2016.11.4.22905 Single Phase to Single Phase Step-Down Cycloconverter for Electric Traction Applications Mrs. J. Suganthi vinodhini and R. Samuel Rajesh Babu Research Scholar, Sathyabama University, India Abstract: In electric traction application electrical energy used was: 1.direct current and 2.alternating current. In this world already a constant voltage constant frequency single phase and three phase AC readily available. For some applications it is needed to have variable voltage and variable frequency for this conversions need between dc and ac sources and this conversion can be carried out by power converters. For converting AC–AC cycloconverter are widely used as a converter. The ns of alternating current drives relates with the frequency (f) and number of poles (p) present in the induction motor. It is not feasible by changing the poles of a motor under running processes, so the only one way during running condition the frequency can be varied. In the absence of direct current (DC) link with constant voltage constant frequency alternating current to variable voltage variable frequency alternating current is needed to run the electric traction applications, so the cycloconverter will make this as possible with reliable and economical. This work explains how to control the speed of single phase induction motor and single phase to single phase Cycloconverter using different frequency conversions with R Load was carried out using MATLAB / Simulink. Key words: Cycloconverter Electric traction Pulse width modulation Synchronous speed (ns ) INTRODUCTION switches instead of thyristors. -
