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.

So up until now, we've seen how a couple of German immigrants came to America and turned their dreams into a reality. Fredrick came to America at the turn of the Century, Hugo a few decades later, and now Otto Kollmorgen had the reins of Kollmorgen firmly in his hands. Just how did these two companies come together? Here is a first hand account from Herb Torberg (Chief Engineer, Kollmorgen). "In the late 1950's, Kollmorgen was very busy updating submarine periscope features capabilities. Submarines were going deeper, faster and the capabilities of the periscope were greatly expanded. Included was the need to take better photographs, including sextant navigation, provide Passive electronic countermeasure, and to aid the operator in training (turning) the periscope."

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.

Over the next few months, we will be publishing a blog series about how Kollmorgen evolved from its humble beginnings to today. Follow us on this journey and learn about the visionaries that built the foundation of our company.

Turn back time – to the 1900’s, the turn of the century, the industrial revolution in full force. A young man who was skilled in optics left his homeland of Germany to work under the auspices of optics pioneer, Karl Reichert in Vienna. Frederick Kollmorgen decided to bring his skills to America, passing through London with a brief stint with Ross, Ltd. Kollmorgen settled in New York, providing optic skills for Keuffel & Esser, who manufactured drafting and surveying instrumentation.

Today’s blog is part of a Throw Back Thursday post – about an article I wrote for SubNotes magazine back in 1988. At the time we had completed a number of submersible motor applications for some very unique and tough environments. Applications with interesting names like Alvin, Jason Jr, or Robin – the first, a manned research vehicle at the time operated by Woodshole Oceanographic Institute, the other two, remotely operated submersibles used to explore the wreck of the Titanic, among other adventures.

Among the simplest and least expensive feedback devices are Hall-effect sensors.  These are digital on-off devices that detect the presence of magnetic fields.  Made of semiconductor material, they are rugged, can be operated at very high frequencies (equating to tens of thousands of motor rpm), and are commonly used to provide six-step commutation of brushless motors.

Noise, and I'm not talking about that terrible band you heard at the summer fest last year, but electromagnetic interference (EMI) noise. There are 8 key steps to consider when trying to eliminate EMI noise issues. If you follow these guidelines, you are much less likely to have problems with electrical noise in your application.

Prior to leaving Europe, Fredrick became the proud father of a baby boy – Ernest Otto. This would be the first of three children, the other girls (Hildegard and Dorthea). From various records, I can only piece together a few bits of information regarding the early 1900’s. It appears Frederick’s wife (Agnes Hunt), an English woman, whom he married in Italy, traveled back and forth to the United States from England, bringing the children over at certain times. Otto was born in 1901 and came to the US in 1907, two years after Fredrick immigrated. Hildegard, was born in 1903 and followed to the US in 1910. Finally, Otto’s youngest sister, Dorthea, was born in 1914 in Italy –right in the midst of World War I.
