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, inverters, and control, and addresses modeling, implementation, control strategies, and flux weakening operations, as well as parameter sensitivity, and rotor position sensorless control. Suitable for both industrial and academic audiences, this book also covers the simulation, low cost inverter topologies, and 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 drives, and 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 correction, and inverter control Introduces space vector modulation step by step and contrasts with PWM Details dead time effects in the inverter, and 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 standard, and 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.

ver since Sir W Jones translated Kalidasa's Sakuntalam into English (1789), many scholars from the West have shown interest in Indian Sanskrit literature. By 1847, 607 works had been translated. Among them, the Gita is one of the most translated works. The Gita and Bhagavatam are the essence of the Vedas, the ancient Indian texts of knowledge. While the 700-sloka Gita is written as a discourse to one who wants to choose his duty and duty, the 14094-sloka Bhagavata is described as a discourse to a ruler who is to die in seven days. Like the Gita, translations of the Bhagavatam are not widely available; Whatever is available, they are like a religious work, not like this book. This book is a collection of easy-to-read stories that does not qualify to be called a literary or religious work. The Bhagavatam, which is believed to have been written before the beginning of the Christian era, contains ancient thoughts on Indian science and post-Vedic Sanskrit texts such as the Mahabharatam and the Ramayanam. In this book, the entire Bhagavatam is condensed into eighty stories divided into two parts along with explanatory notes and a glossary at the end. Every care has been taken to preserve the key message in the Bhagavata - Learning, empathy and dispassion as essentials for a happy life.

This book is primarily about the Rgveda, the avowed source text of all Hindu religious texts. It is a collection of 1028 mostly unrelated hymns. The language in which it is composed is known as ‘Vedic’, from which Sanskrit is believed to have evolved later. About a fifth of the poems are prayers addressed to what could be ‘Nature Gods’. Others cover a motley of subjects. About fifteen of these hymns relates to cosmogony, but differing in essentials. Vedic clearly belongs to the Indo-European language family. Apart from many cognate words that are common in all these languages, many of the stories mentioned in the Rgveda have a strong resemblance to mythologies in the other languages of the family; not just to the Zoroastrian ones, but also to those of Greek, Celtic, Nordic, Slavic, Hittite and others. Origin of Vedas also discusses a wide range of issues related to the origin and expansion of the Indo-European language family. The author has managed to collect together a lot of information about the Rgveda; some of which most would not have heard about earlier. Those interested in these may go through chapter 4 and 9.

In agrarian societies land is the most important means of wealth and source of power and prestige. Rights in land are often hereditary with power and prestige. Therefore, changes in the tenurial system and the pattern of ownership will have far reaching effects on the social order. The Indian peasantry appeared as a formidable force against foreign domination after the imposition of British authority. Investigates the impact of British rule in the agrarian relations of Malabar district, in the Madras presidency which came under the direct rule of the British in 1792 and the consequent complexities in landlord tenant relations. The various tenancy legislations and later land reforms in the State of Kerala are also studied. The relations of the Peasant movement with the nationalist movement and the role of the Malabar peasantry in the anti-imperialist, anti-landlord struggles are discussed at length.
In 2014, Prime Minister Shri Narendra Modi launched a monthly radio program, Mann Ki Baat. In a world dominated by social media and television, it seemed a strange choice. Little did the world realize what a masterstroke it was. By 2023, when he completed his hundredth episode, 1 billion people had listened to the show at least once! In this book, researchers from IIT Madras use policy advocacy frameworks and systems theory to analyze Mann Ki Baat and demonstrate that it has gone beyond being just a radio show to being a ‘life-centric living system’. Mann Ki Baat has empowered citizens and brought about transformational capacity of people in India. The book also presents a case study of how the IIT Madras ecosystem has built transformational capacity around innovation and entrepreneurship.
