Electric machines are often synonyms for electric motors and electric generators. The term refers to those devices that has certain mobility but furthermore, to those that transform electric currents into motion or motion into electric currents. The modern society depends upon energy to subsist, this energy comes from a number of different sources, some very polluting, like burning fossil fuels, others very low polluting - at least during energy harvesting – like solar cells, and in between, lies the inductive generators. This machines take advantage of mechanical energy, for instance water sources and wind power, and convert part of this energy in electric currents.

The synchronization and control of these machines is complex, not only from the mechanical point view, but electronically. The engineer accounts for duty cycles, torque potential, cost, efficiency and magnetic core assembly among others, and the advances in these fields is growing fast. Electric Machines Principles, Applications, and Control is intended for students and engineers, as well as materials scientists will find this book to be a good comprehensive resource for learning about the fundamental control and functioning of these machines, focusing on specific examples that are also top research material in the area, suitable for the interested reader. Content coverage of the book is as follows. First chapter provides an overview of non-rare earth permanent magnets for traction motors and generators. The purpose of second chapter is to investigate the feasibility of using surface magnetic Barkhausen noise for the evaluation of AC core loss, and further, to examine potential origins of magnetic loss in non-oriented electrical steel. Third chapter presents the fault-tolerant control problem of DC motors. In fourth chapter, the application of type-2 fuzzy logic concepts to the position control of a simple DC motor were illustrated. Fifth chapter covers dynamical simulation of a nonlinear stepper motor system. Sixth chapter describes the performance of DI-BSCCO superconducting electric motor. In seventh chapter, work power factor and total harmonic distortion of separately excited DC motor controlled with AC-DC converter has been analyzed at-load. Eighth chapter proposes a method for the identification of inductive motors load partition based on coherence and ninth chapter aims to present dissimilar stator faults which are classified under electrical faults using motor current signature analysis (MCSA) and the comparison of simulation and hardware results. The aim of tenth chapter is to provide energy efficient control of three-phase induction motor drive and eleventh chapter deals with performance analysis and implementation of a three phase inverter fed induction motor (IM) drive system. The purpose of twelfth chapter is to propose a fuzzy logic speed controller of induction motor where flux and torque decoupling strategy is decoupled in terms of magnetizing current instead of stator current to alleviate the effects of core loss. Thirteenth chapter focuses on Ethernet control AC motor via programmable logic controller (PLC) using LabVIEW. Fourteenth chapter presents the capacity variation effect, speed of drive and load as function of the wind system without and with analogical regulator. Fifteenth chapter proposes a new type of the synchronous capacitive machine operated on a principle of the electric field effect. In sixteenth chapter calculations of the varying inductances profile for a synchronous linear surface mounted permanent magnet generator has been presented and seventeenth chapter explores on the steady state analysis of a double-fed induction generator (DFIG) adopted for wind power generation. Eighteenth chapter deals with high efficiency double–fed induction generator applied to wind power generator technical analyses and nineteenth chapter highlights new development in the performance improvement synchronous motor. Twentieth chapter describes a converter control to contribute to enhancing the synchronizing torque. In last chapter, a model of a variable speed wind turbine using a permanent magnet synchronous generator (PMSG) is presented and the control schemes are proposed.
