Right-Sizing Motion: Kollmorgen Pushes Back on Over-Specifying High-Voltage Systems

In industrial facilities, 400–480V three-phase power is standard. Manufacturing plants, automotive production lines, logistics hubs, and high-throughput packaging facilities are all typically built around that infrastructure. For machine builders, the question isn't whether to work with high voltage — it's how to design motion systems that take advantage of it without adding unnecessary complexity.

The over-specification trap

The common assumption is that high-voltage environments demand high-spec motion systems everywhere. Historically, working within high-voltage environments has often meant moving toward more complex motion platforms designed for maximum performance.

"This doesn't mean every axis within a machine needs to be designed to the same high specification."

The company's point is practical. Not every axis in large industrial environments requires the highest levels of power or performance. Many handle positioning, guiding, or material handling — essential tasks, but not ones that justify top-of-the-line hardware. Going the other direction doesn't work either: introducing lower-voltage systems into high-voltage environments can add unnecessary complexity of its own.

"The challenge isn't in adopting high voltage, but in making the best use of it."

Complexity has a real cost

More complex systems tend to demand more from the people working with them, taking longer to configure and requiring more specialist knowledge. Crucially, the time required to integrate and commission a system can outweigh the benefits of higher performance on paper. That calculus is shifting buying behavior: machine builders are increasingly focusing on solutions that meet the needs of the application without adding unnecessary complexity.

A scalable platform approach

Kollmorgen's Essentials system is designed to reduce the time and effort required to specify and commission a motion system. The platform is now expanded to include high-voltage options, aligning with standard industrial power — meaning it can operate directly within 400–480V environments.

"The goal isn't to limit capability, but to apply it where it's needed and avoid it where it's not."

The takeaway for machine builders

The most effective solutions are those that fit the application closely and make the best use of the infrastructure already in place. For engineers designing into 400–480V facilities, that means resisting the urge to spec everything to the maximum.

"High-voltage operation has long been a foundation of industrial automation. The challenge now is to ensure that motion systems take full advantage of that foundation – without adding unnecessary complexity along the way."
