The
main purpose of this new edition continues to be to provide guidelines for
selecting and utilizing electric motors on the basis of energy efficiency and
life-cycle cost. In previous editions of this book, particular emphasis was
given to three-phase and single-phase induction motors in the 1–200 hp range
since this was the range offering maximum opportunities for energy savings.
New
electric motors such as brushless DC and switched reluctance have also been
mass-produced and made commercially available. The impetus toward this
expansion of power electronics has been provided by recent advancements in the
areas of solid-state switching devices, control electronics, and advanced
microcontrollers, microprocessors, and digital signal processors (DSP). These
advancements facilitate high-tech applications and enable the introduction of
power electronic converters with highest performance, maximum efficiency, and
minimum volume and weight.
In
this edition, Chapters 1, 2, 4, 5, and 7 from the previous editions
have been updated, rearranged, and revised. These chapters present
energy-efficient single-phase and three-phase induction motors comprehensively.
Chapters
3, 6, 8, 9, and 10 are new.
Chapter 3 presents the fundamentals of power electronics applicable to electric
motor drives. Adjustable speed drives and their applications are explained in Chapter 6. Advanced permanent magnet (PM) and brushless DC (BLDC)
motor drives as well as switched reluctance motor (SRM) drives are presented in
Chapters
8 and 9, respectively.
Finally, utility interface issues including power factor correction (PFC) and
active filters (AF) are discussed in Chapter 10.
