Industrial Servo Control Systems: Fundamentals And Applications, Revised And Expanded
Written by a seasoned expert, this authoritative and informative guide presents the technologies in the calculation of brushless DC motor time constants, material on drive sizing, and case studies illustrating key topics. The author details hardware specifications related to the operation of machine service drives and outlines troubleshooting methods for problems concerning machine nonlinearities, inertia, drive stiffness, and friction. He highlights recently developed simulation methods used to predict, assess, and improve the performance of service systems and their components and covers the function and assembly of drive systems, drive resolutions, drive ratios, and duty cycles.
