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.

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.

### How to Calculate RMS Torque

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.

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.

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

09 Aug 2016

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.

### 3 Key Reasons For Not Taking Shortcuts for Motor Repairs

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 Story of the Sphere

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?

### Cooperation Between Industry and University - An Update

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.

### Food Recall Hits Close to Home

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.

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

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
