In "A Man Named Good" we follow the life of a human whose name becomes a concept in the future. The main character lives in a small village that is surrounded by trees and bushes of the wilderness, isolated from most of the world he lived a life full of curiosity, adventure and wonder. Until one day a stranger arrives at the village and by presence alone introduces a new and different way of living. Is the stranger the reason for the mistranslation of actions and words that we accept today as the norm? Let us take a moment to see where the word "Good" has actually come from it may surprise you.
Linear electric actuators (LEAs) and linear electric generators (LEGs) are widely used electromagnetic devices. This book deals with LEAs that convert electric energy into controlled mechanical motion of limited travel and LEGs that transform mechanical energy into electric energy. Examples range from loudspeakers and microphones to magnetically levitated material transfer in ultraclean rooms. Much of the literature on linear actuators and generators covers the principles of operation and performance calculations of these devices. Little has been published on their control or on detailed design methodologies. This book presents the first unified treatment of the subject, including the construction, operation, control and design of LEAs and LEGs. Chapters describe linear induction, permanent-magnet, linear reluctance, switched reluctance, and linear stepper actuators, as well as various types of linear electric generators. The text is amply illustrated with numerous design examples.
