Query: Everything you would need to know about motors

I took on a freelance job and needed to get more detailed information/advice regarding motors and motor control. This book was all I needed. It's very informative and well written. It teaches you about the types of motors, how to select the right motor for your application, and finally how to control them using different kinds of circuits and integrated circuits. If you want to know the mathematical details of torque, how to measure your motor's torque, or how to decipher motor specs, it is all in this book.This book will be a great reference even for someone who already has some knowledge of motors.
