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…
Cogging and Torque Ripple questions are common and many times, difficult to answer.
Cogging torque is defined as the attraction/interaction of the magnetic poles to the teeth (steel structure) of the laminations within an un-energized motor.
Torque…
The American Meat Institute generated a Fact Sheet related to Sanitary Equipment Design in 2008 which helps the OEM Machine builder to design sanitary solutions for the Food Processing and packaging market. Our blog post looks at the 10 sanitary…
Washdown applications can be quite the tough environment. In the first place, typically you’ll find washdown requirements on machines that process foods. You know how careful you are when cooking at home, making sure you wash your hands after…
Consumers expect safe food. The Feds expect a safe food supply chain-farm, processing, packaging, and distribution. As we all work to consistently meet consumer food safety expectations, the need to prevent and control food adulteration…
When a load is driven directly by the motor, the conversation around reflected inertia goes out the window. The belief is that direct driven loads do not, by their nature, have a reflected inertia. Some folks are even confident enough to say that the…
There are challenges for a servo motor's protection against overheating by the manufacturer, machine designer/OEM, and user, because there is no thermal device that can protect a motor against a fast transient event. For just as there is a time…
There is a lot of energy [pun intended, sorry] going into the design of next generation, high temperature, Down-Hole motor technology at Kollmorgen. The existing motor technology available in the marketplace has basically been the same since the…
Electric motors are used in machines and processes all around us. You can find them in factories, automobiles, airplanes, robots and even your favorite DVD vending machine. Regardless of the application, managing heat dissipation is a…
While all of this work by Fredrick Kollmorgen was going on another immigrant, named Hugo Unruh, was growing up in Germany. About the same age as Frederick’s son Otto, Hugo faced the harsh conditions in post WWI Germany with its rampant inflation and…
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…
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…
There really isn't anything to fear when utilizing high performance frameless servo motors in your machine design. Many engineers get concerned about "air gaps" and "concentricity" when discussing frameless servo motors - but there is little to be…
