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!

The human vs. robot topic in workplaces has been in the spotlight for quite a while. Look at the comments under the YouTube video where Google introduced its AI (Artificial Intelligence) assistant that could call restaurants and salons to make appointments - there is widespread concern from the audience over the risk of human workers being replaced by AI-equipped machines. But on the other hand, even Elon Musk admitted in a Tweet that “humans are underrated” at Tesla, where “excessive automation was a mistake”. Inspired by such arguments, I keep pondering over one question: what is the role of robotization, or automation in a broader sense, in today’s employment?

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.  
A few years ago I watched the DARPA challenge. If you’re not familiar with the challenge, the idea was to build a robot that could drive a car, climb a ladder, turn a handle, use a drill and various other activities.  In the challenge each robot was given an hour to complete the tasks.  It was a slow process. I had two reasons to watch, one, Kollmorgen has some frameless motors in the Carnegie Mellon robot and two, I’m a Virginia Tech graduate and they also provided a robot.
A collaborative robot (or Cobot) is a robot that is made to work with or interact with human co-workers. For most of us normal folks, the most well-known example is Tony Stark’s robotic arm. (For those reading who are wondering why I don’t refer to the arm as JARVIS, it’s because JARVIS is the AI and controls other things but not the robotic arm.) Tony has bit of an unhealthy relationship with the robotic arm, he insults it, puts it in a dunce cap, puts it in time out, or threatens to dismantle it. At which point the robotic arm usually hangs his robotic limb downward into sadness. But, the robotic arm is there to do work for Tony in his basement. He may have a large house, but he doesn’t want a 10-foot-tall robot behind a fence. He wants an assistant, a co-worker of sorts that can help build his Iron Man suits.
Let’s take a step back and talk about what a DC motor is.  Typically, when thinking about a DC motor, you really are talking about a DC permanent brush type motor.  Apply DC power, adjust the voltage and current levels to control it, usually with a simple amplifier, and you have a dc system solution.  Add in some type of feedback and you will have pretty good control.  There are lots and lots of robot types, but mobile robots are typically going to need to run off of a battery source, thus the need for a DC solution.

Successful CSR (Corporate Social Responsibility) is about action. An often overlooked action to improve CSR is industrial automation with AGVs (Automated Guided Vehicles). Well-known for their quick efficiency gains in industries and warehouses, AGVs such as mobile robots and tuggers also contribute to improving your environmental and social performance.

Until the start of the new millennium, it was customary practice to purchase drives, motors, and cables from different suppliers. Nowadays, connection cables are no longer considered to be an accessory but a product in their own right that requires a level of competency similar to that of any other product. Only the company that designed the motors and drives is in a position to make the appropriate choices to offer its customers a high quality and flexible connection that can be tailored to their application requirements.

Robots and automated machines and vehicles form an integral part of our everyday lives and are not just found in the industrial sector: precise control of motion is indispensable. The combination of the two areas of technology – motion (servo drives) and movement (AGVs) – allows KOLLMORGEN to play a leading role in “Motion in Movement – 4.0 Ready” solutions, and to offer its own customers complete and integrated systems, ready for Industry 4.0.

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.

Automated guided vehicles work repetitively, never get tired and are easy for staff to get used to. An excellent way forward for any company that wants to improve safety at work – and as a bonus increase their productivity.
