Is Brushless Better? 0

brushed vs. brushless

Brushed motors came first — by a long chalk. Ernst Werner von Siemens invented the brushed DC motor in 1856. The brushed DC motor was the only game in town for over a century, till the brushless motor was developed in the 1970s. Indramat’s brushless AC Servo was released in 1979, and quickly became the industry standard for motion control as well as a key to high performance automotive Powertrain manufacture. Rexroth took over Indramat at the end of the 20th century, and has continued to improve brushless motors ever since. Brushless motors don’t require a physical commutator, and suffer [&hellip

Automation is Green 2

Automation for lights, according to Rexroth-Bosch’s research, can save up to 60% in energy consumption. Sounds green? It is. We’re all aware that automation increases throughput and decreases staffing costs, thereby creating greater productivity with lower costs. But did you realize that automation is also good for the environment? The main reason that automation is environmentally friendly is that it cuts down on waste. The lights are an example: it’s not that the lights become vastly more efficient because they’re automatic, so much as that they’re only providing the light that’s actually needed. People decide how much of something they [&hellip

Why Do We Call It a Servomotor? 0

Posted on 27, October 2017

in Category Blog, Indramat History, Indramat Tips

You may call it a servo motor, servo-motor, servomotor, or just a servo. Indramat called their 20th century original an “AC Servo.” Why? While it has been suggested that the French cerveau (brain) might be the root for this term, it’s more likely to be the Latin servus, which gives us (and the French) words like “service” and “serve.” It appears that the term “servomotor” in English did come from the French servomoteur in the late 1800s, and it’s therefore conceivable that the French use of the word included a pun on cerveau, but it’s clear that the “servo” part is [&hellip

What Does Indramat Mean? 0

in Category Blog, Featured, Indramat History

Indramat means excellent drive and control technologies, right? However, it also means “Gesellschaft zur INDustrialisierung-RAtionalisierung und AutoMATisierung” or, in English, “Association for Industrialization, Rationalization, and Automation.” Indramat was born in 1958, when nobody had a computer at home, going to space was the biggest technology goal, and robots were found in science fiction, not in your broom closet. Industrialization, especially in Indramat’s native Germany, meant greater prosperity and greater freedom. Rationalization was a lofty goal, one that made people think of clean, streamlined workplaces without outdated shibboleths (we’re pretty sure they were all thinking about shibboleths). Automation was going to [&hellip

The History of the Printing Press 1

Posted on 10, January 2017

in Category Blog, Indramat History

We work with a lot of clients in the printing industry, so we were fascinated when we found out about the exciting history of the printing press. Seriously. It all started with Johannes Gutenberg in 1440, of course. Up till that time, printing a page meant engraving the whole page in mirror image onto a block of something (usually wood), inking it up, and laying the paper onto it. This was faster than copying a page out by hand many times, but not exactly fast.  Gutenberg came up with a machine that used movable metal type. Letters could be arranged [&hellip

Bosch Rexroth and The Car Industry 0

in Category Blog, Indramat History

Next time you’re driving in your car, remind yourself that without consumer demand for better and safer cars, companies like Bosch Rexroth wouldn’t exist and manufacturing would be years behind where it is now. Car manufacturing has been a huge proponent for manufacturing innovation because of the heavy demands of the industry on manufacturing technology. In a recent article in Drive & Control magazine, Rexroth looked at their history of innovation and the automobile industry. One of the biggest changes in the automotive industry Rexroth is behind is using one automation company to do all the different jobs needed in [&hellip

Dinosaurs and Servo Repair 0

The largest animals to roam the earth are long gone. Servos, however, are still going strong. Since the 1800s, servo motors have been essential. They started out in ships and they’re still important in that field. Newport News recently ordered the world’s largest servo-based pipe bending machine to be made for their shipbuilding manufacturing. This pipe bending machine will be the world’s largest servo motor, but there are more giants out there, including a super huge servo transfer press. Large servo repairs can be more of a struggle than caring for small servos, because their size often increases the complexity [&hellip

Rexroth Bosch in China 0

in Category Indramat History

As the American manufacturing sector begins to recover and manufacturing jobs return to the United States, China has been in the news. Certainly, China comes up as a threat to U.S. manufacturing jobs. American workers can’t compete with Chinese workers on price or on tolerance for difficult working conditions, and China continues to be a popular place for American companies to offshore. China also comes up as a threat to American industry because, with European economies uncertain, China has become an important trading partner. Lower orders from China and speculations that Chinese factories are a saturated market have been among [&hellip

Rexroth Indramat in America 0

in Category Blog, Indramat History

We’ve mentioned before that Rexroth-Bosch, the current owners of the company that used to be Indramat, began with a hammer foundry in 1795 in Elsavatal, Germany. The history of Rexroth in America didn’t begin until much later — almost two centuries later in 1967, when Rexroth Corporation set up as the importer of the German Rexroth products. At that time, Rexroth had just recently acquired Indramat and was still using the name. Within a few years, Rexroth’s American branch had moved to Bethlehem, Pennsylvania, and in 1975 they began to produce some valves there. There is still a hydraulics outfit [&hellip

Getting to Know the Indramat DKR 0

Posted on 5, September 2012

in Category Blog, Indramat History, Rexroth Service

The Indramat DKR drive is specifically designed for high power, high stiffness applications such as printing, packaging, and textile operations. Essentially, the DKR drives were an outgrowth and an upgrade of the classic Indramat RAC drive. Bosch-Rexroth still makes this family of drives and controllers, using HMV-R as the new name. DKR drives can handle motor resolutions of up to 1/4,000,000 of a rev. They work with a number of different interfaces and loop control may be internal or external. As with most Indramat drives, the power supply module for the DKR can supply a variety of drives with different [&hellip
