دانلود کتاب Electromagnetic Devices for Motion Control and Signal Processing

This book presents an analytic tool for examining the design of small electromagnetic devices such as machines, encoders, magnetic strip lines, and other devices. The geometry and magnetic circuit analyses for these devices is based on a differential equation, called the magnetic transmission line equation, derived from Ampere's Law; it is similar to the electric transmission line equation. The analysis includes both uniform and nonuniform geometries, including nonuniformities resulting from manufacturing errors, and leads to a new class of designs for miniature machines and other devices. The magnetic circuit analysis involves both undesirable characteristics (such as core loss and nonlinear distortion in precise, high-resolution encoders), and also desirable aspects that can be used in the form of AC motor-amplifier integrity, hysteresis motors, magnetic encoders, etc. The more than 125 figures serve to visualize the magnetic coupling geometry, the physics of the conceptual design, and the analytical tools.
