Welcome to Kollmorgen's Blog in Motion. We have been adding information and knowledge to the great web based world for many years - through white papers, technical documents, and even webinars. Kollmorgen enjoys sharing our knowledge with you, as well as identifying other motion related tidbits through our Twitter, Facebook, LinkedIn and YouTube feeds. Our newest source is Blog in Motion, covering a wide range of topics, as well as some interesting contributing authors with lots of Motion experience. If Motion Matters to you, stop by, follow, like, and sign up so you can stay tuned for what Kollmorgen has in store for you!
Electro-Optical/Infrared (EO/IR) Systems are used to provide long distance visual and thermal imaging for a variety of applications. Often used in satellites, planes, and military applications, there are two main components found in EO/IR systems: sensors and the motion system. While both the sensors and motion systems need to be reliable in many environmental conditions, let’s take a look at the 5 Harshest Environments for EO/IR Motion Control Systems.
We cover the top 5 advantages of direct drive motors, where the system or motor is connected directly to the load, versus a conventional rotary system.
We’ve all seen the movies…the one where the ‘intelligent’ robots go off-piste and bring untold chaos to the human race. It never really turns out rosy just as the end credit start to fall. However, regardless of Hollywood’s ‘predictions’, no matter where I go or where I look (as part of my role in Kollmorgen’s Aerospace & Defence team) I am constantly tripping over a growing exposure to robotics and Intelligent robots in the Defence sector; air, land, sea and subsea.
Frameless, or “servo motor kits”, open up numerous possibilities in designing motion elements for your machine related to performance. A frameless motor consists of rotor and stator components which are built into a machine assembly to transmit torque to a load. Many applications which take advantage of a frameless motor are direct driven, which eliminates bandwidth robbing compliance. Effectively, this means you have eliminated torsional losses and any wind-up or spring losses.
These 3 characteristics are crucial when sizing a motor for any application from military to industrial and beyond. In this day and age where everything seems to be getting smaller and more compact, we all want our toys to take up less space, but we don’t want to sacrifice any performance. Let’s use cars as an example. When someone is shopping for a sports car, they may be looking for things like high speed, quick acceleration, low center of gravity, small body, etc. These are all reasonable things to look for in a sports car. However, if someone was to say, “I need a two-door sports car with a top speed of 160mph, but I also need it to tow my 10,000 lb trailer”, we might have a problem. This is the same principle when we’re talking about motors. Just like cars, generally smaller motors have much higher speeds than larger motors. However, the large motors are the ones towing that 10,000 lb trailer, or in our case, exerting the most torque.
What is COTS? If you want info on COTS, let’s assume you’re somehow related to the defense industry. If you’re looking for info on camping equipment, sorry, but you’re probably in the wrong place… COTS is a term that has been thrown around the industry for almost 25 years now, but how is it relevant to us today?
Short for Commercial Off-The-Shelf, COTS describes products that are manufactured and readily available for sale to the public that can be used on defense programs. The Department of Defense defines this in the governing Federal Acquisition Regulation (FAR) as a formal term defining products (and services) that are available in the commercial marketplace that can be bought and used for government contracts.
If you are a supplier of components or sub-systems (Tier 2, 3, etc.) into the Global Defense Market, you understand the high standards this industry sets for your products. Exceptional quality, continuous reliability and long-term sustainability are imperative in an industry where most of the equipment is designed to protect the end-user: The Warfighter.
