Electrical Machines primarily covers the basic functionality and the
role of electrical machines in their typical applications. The effort of
applying coordinate transforms is justified by obtaining a more
intuitive, concise and easy-to-use model.
In this textbook, mathematics is reduced to a necessary minimum, and
priority is given to bringing up the system view and explaining the use
and external characteristics of machines on their electrical and
mechanical ports. Covering the most relevant concepts relating to
machine size, torque and power, the author explains the losses and
secondary effects, outlining cases and conditions in which some
secondary phenomena are neglected.
While the goal of developing and using machine mathematical models,
equivalent circuits and mechanical characteristics persists through the
book, the focus is kept on physical insight of electromechanical
conversion process. Details such as the slot shape and the disposition
of permanent magnets and their effects on the machine parameters and
performance are also covered.
