Inhaltsangabe

This book is dedicated to electrical and mechanical engineers involved with the design of magnetic devices for motion con­ trol and other instrumentation that uses magnetic principles and technology. It can be of benefit to graduate and postgrad­ uate students to gain experience with electro-magnetic princi­ ples and also with different aspects of magnetic coupling mech­ anisms and magnetic circuitry analysis for the design of devices such as electrical servo motors, tachogenerators, encoders, gyro­ magnetic suspension systems, electro-magnetic strip lines, and other electro-magnetic instruments. The rapidly growing areas of production automation, robotics, precise micro-electronics, and pilot navigation place demands on motion control technology in terms of accuracy, reliability, cost effectiveness, and miniaturization. New ferromagnetic materials having quasi-linear and non-linear high-squareness characteris­ tics as well as high-energy permanent magnets, fine lithography, and high-t.emperature superconductivit.y (t.o be expected com­ mercially) motivate the implementation of new motion control components that exploit these new materials and technologies. This book presents classical miniature electrical machine de­ signs as well as several modifications in the geometry of mag­ netic couplings which lead to new motor and encoder design methodologies and other motion control devices such as new coil deposition patterns for incremental and absolute encoders, free spherical gyro suspension in a traveling magnetic field for navigation instrumentation, and magnetic strip lines in combi­ nation with resistive and capacitive media to generate a variety of low-noise LC filters and other signal processing devices.

Reseña del editor

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.
