New edition of the popular reference on machine analysis, focusing on reference frame theory with techniques for derivation of equations

Analysis of Electric Machinery and Drive Systems covers the concepts needed to understand the evolution of electrical and magnetic variables for designing the power-electronic circuits that supply or extract electrical energy from a variety of machines, comprehensively addressing the varied needs of readers in the electric machinery, electric drives, and electric power industries.

This fourth edition has been extensively revised and updated to include nine new or updated chapters on symmetrical three-phase stators, symmetrical induction machines, brushless DC machines, synchronous machines, neglecting electric transients, eigenvalues and voltage-behind-reactive machine equations, direct current machine and drive, and torque control of permanent-magnet and synchronous reluctance machines.

Introductory concepts related to the subject have also been expanded upon, detailing stationary magnetically coupled circuits, energy balance relationships, energy in coupling field, and steady-state and dynamic performance of electromechanical systems. The fourth edition also includes illustrations of the free-acceleration characteristics of induction and brushless dc machines viewed from various reference frames and many other topics.

With problems at the end of each chapter to reinforce learning, the book explores additional topics including:

• Operational impedances and time constraints of synchronous machines, covering Park's equations in operational form and parameters from short-circuit and frequency-response characteristics
• Fully controlled three-phase bridge converters, covering six-step, sine-triangle, space-vector, hysteresis, and delta modulations, along with open- and closed-loop voltage and current regulations
• Motor drives, covering volts-per-hertz, constant slip current, field-oriented, and direct torque control as well as slip energy recovery drives
• Brushless DC motor drives, covering average-value analysis, steady-state performance, and transient and dynamic performance of voltage-source inverter drives

Analysis of Electric Machinery and Drive Systems, Fourth Edition, is a perfect resource for electrical engineering students and an essential, up-to-date reference for electrical and mechanical engineers working with drives.
