ISA publishes book on servomotor sizing

The International Society of Automation (ISA) announces publication of a new technical resource, Servomotor Sizing and Application, by Gary Kirckof, P.E. The detailed book brings together the resources required to analyze key mechanisms and select an appropriate servomotor. Written for mechanical engineers engaged in the design of industrial machinery, this book is also suited to control engineers because it illustrates practical servomotor applications. The motor sizing process is broken down into elementary topics, each explored in depth. Detailed examples are also discussed. Other topics include kinematics, duty cycles, inertia, friction, and mechanics. An analysis of linkages is also discussed using a crank-arm and two-axis parallel robot as examples.

Kirckof has spent the majority of his 30-year career working with automated equipment and assembly lines, and the new book is a result of that experience. He is a registered mechanical and electrical engineer employed by Beckhoff Automation as an application engineer. For more information, visit
