• Welcome to Blog in Motion!

    June 12, 2013, by Ray Butler

    WELCOME to the Kollmorgen Blog. My name is Ray Butler, and I am a believer in “Motion Matters”. I am also someone who you would categorize as a user (reader, researcher, downloader, purchaser) of the web, but until now, not someone who contributes any content.

    Kollmorgen, on the other hand, has been adding information and knowledge to the great web based world for many years. We have a website with technical documentation and white papers. We also connect with you through YouTube, Twitter, Facebook, LinkedIn, Google+, and our blog. If Motion Matters to you, we are trying to reach you in many different ways and provide you information.

  • Whatever Happened to the Pacific Scientific Brand?

    August 27, 2013, by Josh Inman

    All those permanent magnet DC motors, synchronous motors, servo motors, servo drives, stepper drives, oh yeah, and remember the great stepper motors they offered? The one stepper motor was a weird shape. It was octagonal where others are square or round. Hard to forget that one!


  • There are 8 of Them and They Both Begin With "H"

    September 11, 2013, by Emily Blanchard

    What is a laughable offense to the public is a representation of the hidden challenges behind packaging and automation. Sure, the package was mostly correct, it contained 8 buns, they were pre-sliced, and odds are pretty good that the two products weigh the same. The package is at least see-through, so as a consumer, you still know what you're buying. But what if it was a bottle of 50mg heart medication that actually contained tablets of 100mg medication?

  • AKD BASIC - Is It Really That Basic?

    October 17, 2013, by Bob White

    There is a nostalgic group out there thinking about when they first were introduced to the BASIC language. BASIC? What is that? Kind of like today when you say album or 45, or even vinyl – certain “younger” folk will look at you and say “whhaatt?” – after they pull the ear buds from their ears and pause there MP3 players. BASIC – Beginner’s All-purpose Symbolic Instructional Code. I first used Basic to program a computer back in 1976, and it had already been around for over 10+ years at that point.

  • New and Interesting Applications deriving benefits from Servo Technologies

    November 04, 2013, by Scott Evans

    Moore's Law has long applied to advancements in technology-based industries. Servo- and Automation have benefited particularly from exponential advancements in memory as well as processing power, and most recently, astounding gains in sensor technology performance vs. price. Here is one definition of a servo system that I will use to limit the scope of what I share in this and future blog posts:

  • How Many Years Does It Take to Move a Pinball Machine Inside?

    February 20, 2014, by Emily Blanchard

    It sat outside for over a year, the very large wooden crate that looked like a step stool for a giant. The folks taking breaks occasionally would question what was in it. But at some point it just became the thing sitting out on the porch. Then one day we decided to open it, so off the back came

  • Food Recall Hits Close to Home

    March 18, 2014, by Emily Blanchard

    Normally my blogs are light hearted and meant to provide some thought provoking ideas in entertaining ways. Today's blog does not have that tone. On February 21st, a recall for a soft cheese was issued due to high amounts of Listeria monocytogenes. Virginia and Maryland have been investigating the products from the manufacturer, but the sad truth is there has been a death associated with this disease. Adding to the sadness is that the CDC is not reporting the age of the person who died, but nearly half of the reported sick were newborns.

  • Cooperation Between Industry and University - An Update

    April 17, 2014, by Bob White

    This blog was originally posted back on June 18, 2012 - I wanted to update this with some new activities regarding our work with Universities since that date...

    There has been a long standing cooperation between Industry and Academics throughout the recent centuries. Just look at the companies that pop up near Universities - like the Route 128 corridor near MIT, or Silicon Valley's influence by Stanford, UCB and UCSF. Every major research university houses a "technology park" filled with start-ups incubating their new ideas and inventions. But it's not just the entrepreneurs that latch on to collaboration with academics. Established firms also find it beneficial to work with universities on various projects of interest, especially where an emerging industry may be getting ready to take off.

  • The Story of the Sphere

    October 30, 2014, by Emily Blanchard

    So everyone’s heard the phrase “think outside the box.”

    And at Kollmorgen we do that. But the reality is we have to think about inside the box. It’s our job to protect inside the box. Our OEMs need us to be ever conscious of inside the box so that the box works and is dependable. But OEMs also look outside the box - does it fit, is it smaller, what’s the advantage?

  • 3 Key Reasons for NOT Taking Shortcuts for Motor Repairs

    February 02, 2015, by Paul Coughlin

    Brushless AC servo motors and stepper motors have long life spans, which are largely due to the lack of wearing components. Unlike brush type motors, other than the bearings, brushless AC servo motors and stepper motors have no wearing components. Additionally you do not have conductive brush dust, which, as it collects on the commutator, may short the armature. The radial and axial loading requirements of step and servo motors are based upon the shafts of the motor, which are usually far less than what the bearings are designed to handle, which provides for a healthy motor life span. However, occasionally motors do need to be repaired. Either a feedback device goes bad, or some kind of electrical mishap may cause the drive to provide too much current, which may damage the winding, or it could be as simple as the bearing grease drying up.

  • What is horsepower and how is it utilized with servo motors

    August 09, 2016, by Hurley Gill

    Horsepower (hp) is a measure of power, which can be further described as the rate at which work is performed. There are slightly different definitions for its conversion to the unit watts depending on the mechanism being described: mechanical, electric, boiler, metric, etc.. Our focus here will be on servo motor systems.

  • How to Calculate RMS Torque

    February 07, 2017, by Hurley Gill

    In our last Block and Tackle posting, we touched on operating a motor in a hotter ambient temperature. For this posting, we take a look at the Root Mean Square (RMS) Torque and why it is important. Typically an axes’ motion profile is broken up into multiple segments, each segment is found to require a specific torque for a specific amount of time to complete the desired motion. For example this can include torque required to accelerate, traverse (against an external force and/or friction), decelerate, and dwell. Each of these segments affects the amount of heating the motor experiences and thus the equivalent steady state continuous requirement utilized to select the correct motor.

  • What Does TENV (Totally Enclosed Non-Ventilated) Mean?

    March 16, 2017, by Emily Blanchard

    Block and Tackle Series Volume 4 – What does TENV (Totally Enclosed Non-Ventilated) mean?

    Question: What does TENV, or Totally Enclosed Non-Ventilated mean in regard to a servo motor?

    Answer: Well – the answer is simply the motor is Totally Enclosed, and Non-Ventilated. Based on NEMA (National Electrical Manufacturers Association) definition, TENV states that the motor housing is fully enclosed and is not ventilated with a fan.

  • What is a Linear Actuator?

    September 11, 2017, by Jimmy Coleman

    Question: What is a linear actuator?

    Answer: Quite simply, a linear actuator is a device that moves a load in a straight line. Linear actuators come in many styles and configurations – our blog post today covers those actuators associated with motion control.

  • What is Mechatronics?

    October 04, 2017, by Bob White

    Mechatronics is taking a holistic look at a complete machine solution, taking account of all elements that make up that system that are part of the machine, including mechanisms, motors, drive electronics, controls, interfaces, and ergonomics. A variety of disciplines are involved when considering a machine design utilizing a mechatronics approach. It is a melding of the physical expectations of a motion system whether mechanical, electronic, hydraulic, pneumatic or any hybrid of technologies used to accomplish a physical task. Often, these systems are trying to duplicate, simplify, or assist a human function, most often a repetitive motion that a machine can do better.

  • Types of Linear Actuators

    October 11, 2017, by Jimmy Coleman

    Last time in our Block and Tackle Series on “What is a Linear Actuator?” we identified the general types of mechanisms that are used to move loads in a straight line. Today’s blog expands on that just a bit with a few more details on the different types used in the motion control world.
