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, Google+, 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!


  • 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.

  • In our last blog related to decentralized drives, we indicated several key customer benefits tied to using this approach.  First, you can reduce your cable costs significantly in machine configurations with lots of axes spread apart throughout the machine.  Second, a reduction in cabinet space and cooling requirements since you’ve taken a number of heat producing elements (Servo drives) from the enclosure.  Thirdly, you increase flexibility in design. In this blog entry, we will explore what is meant by flexibility and how this offers several advantages.

  • Less Cabling, Smaller Cabinet, Less Heat…More Flexibility!  Less Cabling, Smaller controls cabinet, Less heat…wow, that’s all great stuff.  I can achieve this all with a decentralized solution?   Absolutely – and even more! Decentralized Control Architecture means shifting the motion control drives from the crowded cabinets, and moving them near to the motors – out on the machine where the action is.  Immediately you can see that this can reduce the size of the controls cabinet, moving all of those drives out onto the machine – but how do I see these other advantages?

  • 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.

  • 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.

  • The FSMA evolution is ongoing and Kollmorgen continues to enable innovators to meet the requirements of making food production and packaging safer.  Kollmorgen’s White Paper “Food Safety Regulatory Requirements”  explains the background of FSMA as well as the implications on machine design.  We recognize that not all facilities have the ability to build a completely new plant from the ground up.

  • How do I calculate a motor’s continuous torque when it is operating in an environment above its rated temperature? Since the motor’s continuous torque (Tc) is rated in a 40°C ambient, how can I estimate the motor’s continuous torque during my worst-case ambient temperature of 55°C?  

  • Collaborative robots are designed to work safely with and next to their human counterparts.  A subset of collaborative robotics has innovative safety techniques that completely eliminate the need for a safety barrier between the human and the robot.  This enables a wide range of applications to deploy and benefit from this collaborative robot technology.

  • We are excited to introduce the launch of a brand new product selection tool – Kollmorgen Stepper Optimizer. Optimizer provides multiple ways for you to discover what Kollmorgen stepper motor works best in your application. Comprised in the tool are Kollmorgen’s most highly recommended stepper series. This includes our newest stepper product, the PMX Series, as well as our  popular Powermax and POWERPAC product families.

  • 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.
