Every solution comes from a real understanding of OEM challenges

Every solution comes from a real understanding of the challenges facing machine designers and users.

The ever-escalating demands of the marketplace mean increased pressure on OEMs at every turn. Time constraints. Demands for better performance. Having to think about the next-generation machine even before the current one is built. While expectations are enormous, budgets are not. Kollmorgen’s innovative motion solutions and broad range of quality products help engineers not only overcome these challenges but also build truly differentiated machines.

Because motion matters, it’s our focus. Motion can distinctly differentiate a machine and deliver a marketplace advantage by improving its performance. This translates to overall increased efficiency for your application. Perfectly deployed machine motion can make your customer’s machine more reliable and efficient, enhance accuracy and improve operator safety. Motion also represents endless possibilities for innovation. We’ve always understood this potential, and thus have kept motion at our core, relentlessly developing products that offer precision control of speed, accuracy and position in machines that rely on complex motion.

Optimized Solutions

Whether it’s modifying a product from our standard product portfolio or a white sheet design for a custom solution to achieve true optimization, you can rely on decades of Kollmorgen expertise to solve your motion challenges and help you build a differentiated machine

Standard Products

Because our application expertise runs deep and our product portfolio is so broad, we can take any standard product or existing design baseline and modify it a lot or a little to suit many needs – in a very rapid time frame. This approach ensures quality, performance and reliability by leveraging our proven track record.

Kollmorgen application engineers have a great deal of experience helping OEM engineers achieve their objectives. Typical modifications of frameless kit motor designs include winding changes, tailored mounting features, diameter and stack length adjustments, material changes, insulation changes, magnetic circuit optimization, lead bundle changes, commutation sensor choices and thermal sensor choices.

Custom Products

With motion as our core capability, we bring a significant history of innovation to today’s engineering challenges. We leverage our design and engineering excellence and technical knowledge to deliver creative new solutions for virtually any need.

Removing the Barries of Design, Sourcing, and Time

At Kollmorgen, we know that OEM engineers can achieve a lot more when obstacles aren’t in the way. So, we clear obstacles in three important ways:

Integrating Standard and Custom Products

The optimal solution is often not clear-cut. Our application expertise allows us to modify standard products or develop totally custom solutions across our whole product portfolio so that designs can take flight.

Providing Motion Solutions, Not Just Components

As companies reduce their supplier base and have less engineering manpower, they need a total system supplier with a wide range of integrated solutions. Kollmorgen offers complete solutions as well as motion subsystems that combine programming software, engineering services and best-in-class motion components.

Global Footprint

With direct sales, engineering support, manufacturing facilities, and distributors spanning the Americas, Europe, Middle East, and Asia, we’re close to OEMs worldwide. Our proximity helps speed delivery and lend support where and when they’re needed.
