Kollmorgen’s brushless servo motors offer the highest torque/inertia ratio over a broad range of speeds—including high speed capabilities up to 8,000 rpm for standard designs and up to 70,000 rpm for special designs.

Kollmorgen introduces the next generation of motion for more ambitious machines built on more capable performance and more confident engineering. The Kollmorgen 2G Motion System harnesses the full performance potential of our leading AKM2G servo motors and perfectly matched AKD2G drives designed to deliver unrivaled power density and control. The result is significantly enhanced torque, responsiveness and SafeMotion capabilities in a compact footprint that enables easy installation and total flexibility.

AKM2G represents the latest evolution of the industry-leading AKM motor family. With significant torque increases in the same motor size OEMs can achieve substantial performance improvement without changing the motor mounting or using more machine space.

Our best-in-class, high-performance servomotors offer a wide range of mounting, connectivity, feedback and other options. More than 500,000 standard models are available along with co-engineered modifications to suit almost any application requirement. Gearmotor, washdown and food-grade versions are available.

The AKMH Series is built to withstand the most rigorous of washdown regimens. The combination of the AKMH’s IP69K construction and corrosion resistant materials make for a servo motor that will last the life of your machine.

AKM and AKM2G Low Voltage servo motors are designed for high-performance, demanding dynamic applications which require 24-96 VDC bus input.

The Kollmorgen Goldline® Series provides optimum performance for applications that involve rapid acceleration/deceleration, compliant loads or large inertia mismatches. These motors are available for 230 and 400/480 VAC line voltage. We also offer explosionproof, washdown and submersible models.

These enhanced, high performance motors are MilSpec 810E rated and IP67 sealed. They are supplied standard with a stainless steel shaft and chemical agent-resistant paint for reliable duty in harsh environmental conditions.

While these servomotors are not available for new applications, Kollmorgen continues to provide replacement motors and support for existing customers.

Kollmorgen pioneered the development of direct drive technology. Today, our Direct Drive Rotary (DDR) and Direct Drive Linear (DDL) motors bring you industry-leading performance, zero maintenance, clean mechanical assembly, improved accuracy, higher throughput, better reliability, and smooth, quiet operation.

Our exclusive Cartridge DDR® servomotors combine the performance advantages of a frameless motor with the ease of installation of a full-frame motor. The advanced electromagnetic design provides up to 50 percent more torque density than comparably sized conventional servo motors.

Housed DDR servomotors offer high torque density, precise performance and zero maintenance in an easily installed servo solution.

The KBM series offers high performance, long life, simple installation in a motor kit that can be embedded directly in your mechanical design. A huge selection of standard motors and cost-effective modifications ensure a perfect fit.

Our TBM series provides direct drive frameless motors designed to be directly embedded in the mechanical structure of your systems, minimizing weight, size and inertia without sacrificing performance.

The frameless configuration of these relatively high-torque, low-speed, pancake-style motors eliminates shaft, bearings, endbells and couplings for reduced volume, weight and complexity when integrated directly with the load.

A Direct Drive Linear (DDL) motor is basically a rotary motor that is laid out flat and directly coupled to the driven load, eliminating the need for ball/lead screws, rack and pinions, belts/pulleys and gearboxes.

Our high-performance, brushless, maintenance-free stepper motors provide precise, extremely cost-effective motion control.

The PMX family of hybrid stepper motors offers unmatched versatility through a wide range of standard and customizable options, unmatched value through exceptional performance at an affordable cost, and unmatched reliability through Kollmorgen’s superior motion expertise and build quality.

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.

KBM™ Series Frameless Motors

The KBM™ Series provides low- and high-voltage motors (120–480 Vac) designed to be directly embedded in your machine using the machine’s own bearings to support the rotor. With a huge selection of standard motors—plus our ability to quickly and cost-effectively modify leads, windings, stack lengths and more—you can choose an exact-fit frameless motor that provides simple installation, long life and the highest performance in the most compact space.
