This text explains the operation of magnetic motion devices and provides the basic tools needed for the design of such devices. Among the magnetic fields, fundamentals of lumped circuits, transformers, voice-coil motors, step motors, brushless dc motors, and materials for magnetic devices. Useful as a textbook for undergraduate engineering students and as a reference manual for engineers whose responsibility is the design, analysis, and understanding of the motion devices used in computer peripherals, robotics, and related fields.
