This book is surprisingly complete, yet it is easy to use. Don't get me wrong, this is not liesure reading, but it is one of the most easily understood, yet comprehensive, books on industrial electrical equipment that I have seen in 25 years in the business. It starts with the basic subjects of Electricity, Magnetism, AC Current, Inductance, and Capacitance, and explains them very well in simple concepts. It then moves on to Transformers, Generators, and Motors, explaining how to use them, how to calculate power, torque, etc. Sizing considerations and post-installation calculations are demonstrated. Then the book goes into motor control methods, including control circuitry, older motor controllers, and Solid State Motor Controls (Drives), and even a little bit on Programmable Logic Controllers (PLC's). This book is highly recommended to anyone working in industrial maintenance, drive manufacturers and service engineers, industrial service shops (motors and/or controls), and aspiring industrial system engineers.
