Topics include kinematics, duty cycles, inertia, friction, and mechanics. The analysis of linkages is also discussed using the crank-arm and a two axis parallel robot as examples.
The Author
Gary Kirckof, P.E. has spent the bulk of his thirty-year career working with automated equipment and assembly lines. Servomotor Sizing and Application is a direct result of that experience. He is both a registered mechanical and electrical engineer and works for Beckhoff Automation as an application engineer.
His career started by writing and debugging the programs that ran the equipment. He would talk to the mechanical engineers who designed the equipment to find out how it was supposed to work, the sensors
they had specified, and so forth. He would then write the code for the control system and then bring the machines to life. It became quite clear to him that after power was first applied to the machines, every mistake, omission, and problem that occurred during the concept, design, and assembly process became his problem. There were many problems because the equipment was large custom machines and assembly lines. He had no desire to deal with these problems and had every desire to make his life easier, so to eliminate as many potential problems as he could, he became involved with every step of the process.
One of the problems he often encountered early in his career was undersized servomotors. Servomotors were relatively new to industrial machinery and not many people were familiar enough with them to properly select them. He was discouraged at the lack of available information so he started to compile every piece of information he could find. This book is the result of his research efforts and his experience working with servomotors, and he wishes for it to fill the still-existing information void and to be a useful resource.
