Electric energy is arguably a key agent for our material prosperity. With the notable exception of photovoltaic generators, electric generators are exclusively used to produce electric energy from mechanical energy. More than 60% of all electric energy is used in electric motors for useful mechanical work in various industries. This book presents the modeling, performance, design, and control of reluctance synchronous and flux-modulation machines developed for higher efficiency and lower cost. It covers one- and three-phase reluctance synchronous motors in line-start applications and various reluctance flux-modulation motors in pulse width modulation converter-fed variable speed drives.

This Second Edition extensively covers advanced issues/subjects in electric machines, starting from principles, to applications and case studies with ample graphical (numerical) results. This textbook is intended for second (and third) semester courses covering topics such as modeling of transients, control principles, electromagnetic and thermal finite element analysis, and optimal design (dimensioning). Notable recent knowledge with strong industrialization potential has been added to this edition, such as:

Induction machines (three and single phase), synchronous machines with DC excitation, with PM-excitation, and with magnetically salient rotor and a linear Pm oscillatory motor are all investigated in terms of transients, electromagnetic FEM analysis and control principles. Case studies, numerical examples, and lots of discussion of FEM results for PMSM and IM are included throughout the book.

With its comprehensive coverage of the state of the art, this Second Edition introduces basic types of transformers and electric machines. Classifications and characterization—modeling and performance—of power electric transformers (single and multiphase), motors and generators, commercial machines (dc brush, induction dc excited synchronous, PM synchronous, reluctance synchronous) and some new ones (multiphase ac machines, switched reluctance machines) with great potential for industry with rotary or linear motion are all treated in the book.

The book covers, in detail, circuit modeling characteristics and performance characteristics under steady state, testing techniques and preliminary electromagnetic-thermic dimensioning with lots of solved numerical examples and special cases to illustrate new electric machines with strong industrialization potential. All formulae used to characterize parameters and performance may be safely used in industry for preliminary designs and have been applied in the book through numerical solved examples of industrial interest.

Linear motion is richly present in various industries, from direct electric propulsion in urban and interurban people movers on wheels or on magnetic “cushions” (MAGLEVs) to indoor transport of goods (conveyors, etc.), through plunger solenoids (to open hotel doors and as electromagnetic power switches), to compressor drives by linear oscillatory permanent magnet (PM) motors, smart phones integrated microphone and loudspeakers, and controlled vehicles’ suspension, etc. Besides the traditional rotary motor drives with mechanical transmissions, which mean friction limitations (weather dependent) in traction (heavy vehicles), more losses, positioning errors (backlash) in the process, and higher maintenance costs to handle them, linear motion in industry by direct electromagnetic forces is free of friction limitations for traction, free of mechanical transmission, and thus more efficient, with less maintenance cost and fewer positioning errors (backlash). This explains why they are used in so many applications already since the dramatic advancement of power electronics and digital control in the last four decades.

Modeling, performance, design, control, and testing of linear electric machines (LEMs) show notable differences with respect to rotary electric motor drives, which warrant a dedicated treatment of these aspects.

The Second Edition (First Edition: 2013) concentrates on the above technical aspects of various types of LEMs in close relationship with specific applications via numerical examples of modeling, design, control, and testing, with ample representative results from literature, industry and some of the author’s contributions, such as:

Technical field and circuit modeling of linear induction motors in flat configurations for low and high speeds (with and without dynamic end effects) and in tubular configurations short travel design, control and testing

Linear synchronous motor (LSM) drives in dc-excited, homopolar, reluctance and superconducting excitation configurations for urban and interurban high-speed vehicles propulsion and integrated propulsion and levitation (in MAGLEVs) modeling, design and control with full-scale numerical examples, with emphasis on lower KWh/passenger/Km at high speeds

Flat and tubular linear permanent magnet (PM) synchronous motors (L-PMSMs), mainly destined to industrial indoor transport for automation at high efficiency in clean rooms

Linear “flux-modulation” motors— new breed, suitable for very low-speed applications due to higher thrust density

Plunger solenoids in various applications including new valve PM actuators with millisecond response time

Linear resonant PM oscillatory motors design, control and testing mainly destined to compressors for higher efficiency in compact drives

Attraction and repulsive force suspension (levitation) systems for MAGLEVs

Active and passive guideway MAGLEVs in urban and superhigh-speed interurban transport at lower Kwh per passenger/km (in lighter vehicles without wheels)

The numerous numerical design and control examples (with practical specifications) throughout the 23 chapters of the book allow the reader deep and fast access to a practical but thorough unitary (good for comparisons) methodology in designing and controlling LEMs for various applications.

Electric Drives, now at 4th edition, provides a practical guide in understanding the fundamental principles and recent new knowledge of electric motion (in motoring) and electric energy flow (in generating) digital control via power electronics for energy savings and increased productivity in practically all industries, from intelligent watches, phones, to robots, electric transport, industrial processes, modern distributed electric power systems with ever more renewable energy penetration.

A restructuring by unification of a few Chapters, the elimination of one Chapter (rectifier d.c. brush motor drives) and the introduction of new paragraphs in most Chapters (many as inspiring case studies) and a brand new Chapters on “Flux-modulation machine drives” (Chapter 8) and on “Predictive Control of a.c. drives” (Chapter 15), reflects this knowledge updating effort.

Though inevitably math – intensive, to be directly usable, the book, mainly intended for senior undergraduate, graduate students and engineers in R&D in industry, is a practical, easy to assimilate, up-to-date synthesis of basic and advanced power electronics (variable speed) electric motor – generator drives needed in all industries where electric energy flow wise – mainly – digital intelligent, control is paramount.
