Book Description
In developing economies such as India, improving the efficiency of home appliances is of high priority in locations which are characterized by a weak electric distribution system. Ceiling fans are one of the most used home appliances in India. They typically operate for many hours, and since most of them are driven by inefficient, low cost single phase induction motors, the total power loss is nontrivial. To overcome the inefficiency of single phase induction motors, brushless dc motors have been increasingly used in ceiling fans to achieve high efficiency and power factor at multiple speed settings. However, they are more expensive than conventional ceiling fan motors due to the additional cost of permanent magnets and power electronic drive circuit. Three phase in contrast to single phase induction motors have proven to have a superior performance especially for high power applications. From a manufacturing point of view, they are no more expensive to build than single phase induction motors. Also, three phase induction motors require no permanent magnets, which makes them economically attractive. To be able to use three phase induction motors in home appliances at variable speed, a power electronic drive is required to convert the single phase supply to three phase. The drive circuit can also be controlled to improve the input power factor. With the advancement of power electronic technology and integrated control devices, such motor drives can be made efficient and cost effective. This thesis explores the design and optimization of three phase squirrel cage induction motors for the application of ceiling fans in India, with the objective of achieving a balance between efficiency and cost. A detailed analytical model for a low speed, low power three phase squirrel cage induction motor is developed. The analytical model is validated using finite-element analysis. This thesis also optimizes the motor design using genetic algorithms. The optimized design weighs 4.5kg and achieves 70% efficiency, which proves more efficient than existing ceiling fan motors in India. The optimized design is also validated in finite-element analysis. Finally, this thesis presents a simulation study of the motor drive implementation for the proposed three phase induction motor.

Book Description
There is not a single industry which will not be transformed by machine learning and Internet of Things (IoT). IoT and machine learning have altogether changed the technological scenario by letting the user monitor and control things based on the prediction made by machine learning algorithms. There has been substantial progress in the usage of platforms, technologies and applications that are based on these technologies. These breakthrough technologies affect not just the software perspective of the industry, but they cut across areas like smart cities, smart healthcare, smart retail, smart monitoring, control, and others. Because of these “game changers,” governments, along with top companies around the world, are investing heavily in its research and development. Keeping pace with the latest trends, endless research, and new developments is paramount to innovate systems that are not only user-friendly but also speak to the growing needs and demands of society. This volume is focused on saving energy at different levels of design and automation including the concept of machine learning automation and prediction modeling. It also deals with the design and analysis for IoT-enabled systems including energy saving aspects at different level of operation. The editors and contributors also cover the fundamental concepts of IoT and machine learning, including the latest research, technological developments, and practical applications. Valuable as a learning tool for beginners in this area as well as a daily reference for engineers and scientists working in the area of IoT and machine technology, this is a must-have for any library.
