Engineers devote a lot of time and effort designing highly efficient, reliable, and economical stepper or servo motor positioning systems. They select a motor, a controller, appropriate feedback circuits, and an amplifier to satisfy the specific motion system’s needs. Unfortunately, however, the signal and power cables connecting the components are often overlooked until the project is nearing its end or, worse yet, handed off to an electrician who lacks the proper training. Overlooking critical cable selection factors can deliver a system with lower than expected accuracy, frequent failures, low immunity from electromagnetic interference, and adverse effects on neighboring equipment.
Grounding and Shielding is an often misunderstood process. It is common to hear quotes ranging from “it's magic!” to “the rules change all the time!” and “there’s no way to understand it!” These emotional statements are repeated but not true. There is a process, it hasn’t changed, and the more one knows about coupling mechanisms the more one will see that it’s sound engineering principals.
Recent work done by Kollmorgen—a global leader in manufacturing motor and motion solutions—has shown that it is possible to synchronize components within the flexo printing process without mechanical transmission by using closed loop control technology. This synchronization is key to managing web tension throughout the process while ensuring a steady repeat length.
Reliability in extreme environments. Optimized motor windings. A larger through-bore aspect ratio. How do you achieve these and other specialized motor attributes on a rapid development schedule, with assurance of meeting cost and supply requirements for a machine that may be marketed and serviced for decades?
An aging population, a growing burden of disease, continuous development of new clinical applications, and global advancements in the standards of disease prevention, early detection, diagnosis and treatment. For all these reasons and more, manufacturers of diagnostic imaging equipment are under extraordinary pressure to produce more innovative machines, capable of more precise imaging, delivered to healthcare institutions of every size, kind and location.
This article presents an overview comparison of stepper motor and servo motor capabilities to serve as selection criteria between the two technologies.
Every radiology department wants to deliver the highest-quality diagnoses to support the highest-quality patient care. The key to improving the patient experience is precise motion under perfect control. That’s Kollmorgen’s specialty.
Few business challenges are as formidable as designing, manufacturing and delivering medical imaging equipment to healthcare organizations around the world. From mechanical and electrical components, to communication and control systems, to motion programming and automation software—every element must be perfectly orchestrated. With more than 100 years of motion leadership, including over 40 years designing, manufacturing and supplying motion products for medical device applications, Kollmorgen delivers motion systems with proven reliability, from initial design through trusted service, to serve the needs of healthcare customers around the world.
This paper reviews options that are available for Ethernet and non-Ethernet connections within the motion controller. It begins with a summary of what information can be transferred in and out of the motion controller followed by network and non-network examples for communicating with controllers. Finally, it presents the factors that need to be considered when choosing the right solutions for your factory.
Washdown is a principal cause of motor failure. OEMs and producers spend a lot of money to protect motors, and lose a lot on downtime. But there’s a better way.
