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.

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.
Linear motors fill an important role in providing a robust and high precision direct drive solution in many high performance applications. In order to achieve the highest level of performance, the linear motor system must be commissioned properly. This blog post addresses key areas to consider when setting up and commissioning a linear motor system. It is always important to refer to the installation and set -up instructions provided by the manufacturer.
Question: I need to operate a servo motor in a vacuum, what are some considerations?
Answer: In a word? Outgassing. You might think that proper motor sizing is a big issue, it always is, however if you can't conform to the other process requirements, there is no point to attempting to size the motor. The biggest issue for any given motor selection to be run in a given vacuum for a specific process is the outgassing requirement, or rather, the avoidance of materials that would affect the process being performed and/or the life of the motor.
I was going over some inventory the other day, and I ran across our old blog of 101 ways to brake your motor -episode 82. The author of that piece, Mike, was just having fun with the title and the number 82. But it dawned on me, that we might be due for another installment.
Let me preface by saying that I am not an engineer. I do however read, on average, about 20 old and new industry articles a week, as well as the content that I share in training and on our social media pages. I have discovered several ways to break motors throughout the years. Some of them have some really great stories and I'll try to get their witnesses to write them down for future blog posts. I have, however, discovered one of the most boring ways to break a motor. And I guess I really discovered it as a child.
