Kollmorgen is your single-source supplier for all the accessories you need to install your complete motor/drive solution.

Accessories for digital Motion Systems in Europe

Drive-to-motor connection methods vary widely depending on rated current and voltage, minimum code distances, different shielding concepts and other factors. We supply pre-assembled ready-to-use cables that meet relevant CE and UL requirements for any power and feedback requirement.

During braking with the aid of the motor, electrical energy is fed back into the drive. If excess energy is not dissipated, an over-voltage fault can occur. A regeneration or “regen” resistor allows your drive to function normally during deceleration.

Collaborative robots (cobots), manufacturing robots and robotic arms are designed to learn and adapt to new tasks as needed, as if they were a human coworker. This requires controlled, safe motion enabled by high quality servo motors inside of the robot joints in order to safely operate beside their human co-workers. The versatility of human/robot collaboration promises to bring new capabilities and efficiencies to industries as diverse as packaging, factory automation, food and beverage processing, life sciences, medical automation and more.

No-Compromise Cobot Design

Cobot engineering has always involved tradeoffs. To get enough torque, do you have to go with a larger, heavier motor? To get enough speed, do you have to accept a steep decline in the torque curve? To get enough of both, do you have to put up with excessive winding temperatures that can damage other components?

Learn how to eliminate these tradeoffs, achieving your ideal torque, speed, size and temperature specifications simultaneously. Read our Blog in Motion, and say no to cobot compromises.

Welcoming the Collaborative Robot (cobot) to Industry

A collaborative robot (Cobot) is a robot intended to physically interact with humans in a shared workspace. This is in contrast with other robots, designed to operate autonomously. A "cobot" is a robot that works in tandem with a human worker. The assumption is that a cobot and a human can produce an end result better and faster than either could do working alone.

Why Choose a Frameless Motor for Your Machine?

Frameless, or “servo motor kits”, open up numerous possibilities in designing motion elements for your machine related to performance. A frameless motor consists of rotor and stator components which are built into a machine assembly to transmit torque to a load. Many applications which take advantage of a frameless motor are direct driven, which eliminates bandwidth robbing compliance. Effectively, this means you have eliminated torsional losses and any wind-up or spring losses.
