Description
T&F India Permanent Magnet Synchronous and Brushless Dc Motor Drives by Krishnan
Despite two decades of massive strides in research and development on control strategies and their subsequent implementation, most books on permanent magnet motor drives still focus primarily on motor design, providing only elementary coverage of control and converters. Addressing that gap with information that has largely been disseminated only in journals and at conferences, Permanent Magnet Synchronous and Brushless DC Motor Drives is a long-awaited comprehensive overview of power electronic converters for permanent magnet synchronous machines and control strategies for variable-speed operation. It introduces machines, power devices, invertersand controland addresses modeling, implementation, control strategiesand flux weakening operations, as well as parameter sensitivityand rotor position sensorless control. Suitable for both industrial and academic audiences, this book also covers the simulation, low cost inverter topologiesand commutation torque ripple of PM brushless DC motor drives. Simulation of the motor drives system is illustrated with MATLAB® codes in the text. This book is divided into three parts―fundamentals of PM synchronous and brushless dc machines, power devices, inverters; PM synchronous motor drivesand brushless dc motor drives. With regard to the power electronics associated with these drive systems, the author: Explores use of the standard three-phase bridge inverter for driving the machine, power factor correctionand inverter control Introduces space vector modulation step by step and contrasts with PWM Details dead time effects in the inverterand its compensation Discusses new power converter topologies being considered for low-cost drive systems in PM brushless DC motor drives This reference is dedicated exclusively to PM ac machines, with a timely emphasis on control and standardand low-cost converter topologies. Widely used for teaching at the doctoral level and for industrial audiences both in the U.S. and abroad, it will be a welcome addition to any engineer’s library.
