Ashfaq Hussain Electrical Machines Book PDF 20

Electrical machines are devices that convert electrical energy into mechanical energy or vice versa. They are widely used in various applications such as power generation, transmission, distribution, and utilization. Electrical machines can be classified into two main categories: direct current (DC) machines and alternating current (AC) machines. DC machines operate on a constant voltage and current, while AC machines operate on a varying voltage and frequency.

One of the most popular books on electrical machines is the one written by Ashfaq Hussain, a professor of electrical engineering at Jamia Millia Islamia University in New Delhi, India. The book, titled Electric Machines, covers the theory and performance of both DC and AC machines in a comprehensive and lucid manner. The book also includes topics such as transformers, synchronous machines, induction machines, fractional horsepower motors, single-phase motors, special machines, and testing of machines.

The PDF file of the book can be useful for students who want to get an overview of the book or to study the first chapter on magnetic field and magnetic circuit. However, it is not a complete substitute for the original book, as it does not contain the rest of the chapters or the appendices. Therefore, students who want to learn more about electrical machines or to prepare for their exams should consider buying or borrowing the original book from a library or a bookstore.
