A TEXTBOOK OF PERMANENT MAGNET SYNCHRONOUS & BRUSHLESS DC MOTOR DRIVES: From Machine Fundamentals to Field-Oriented and Sensorless Control

What separates a motor that merely spins from a drive that delivers exactly the torque you ask for, at any speed, efficiently? >Engineers and students often understand the pieces of a permanent magnet drive in isolation but struggle to make them work together: the machine model, the inverter, the sensing, and the control loops that tie them into one responsive system. >What you will gain- Read and apply the rotating-frame model that makes field-oriented control of the synchronous machine possible- Configure and analyse three-phase inverters, pulse-width modulation, and space-vector techniques- Set up field-oriented current control and extend it into the flux-weakening region for high-speed operation- Choose and interpret rotor position sensing with Hall sensors, encoders, and resolvers, and understand sensorless estimation- Commutate and control a brushless DC motor using six-step and current-control methods- Design a drive to a load specification, checking thermal limits, converter and DC-link ratings, losses, efficiency, and protection- Simulate a drive before building hardware and interpret the results with confidenceInside the book: sinusoidal versus trapezoidal machines; magnetic circuits and energy conversion; machine modeling; converters and modulation; sensing and estimation; six-step, field-oriented, flux-weakening, and sensorless control; and system-level design for applications such as electric-vehicle traction, servo and robotic actuation, pumps, fans, and compressors. Who it is for: electrical, mechatronic, and control engineering students, and practising motor-drive, power-electronics, and control engineers who want a practical yet rigorous working reference. Turn scattered knowledge into a working command of permanent magnet drives. Add this practical resource to your library and start exploring the principles, methods, and applications inside.
