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.
