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.

Led by our next-generation AKD® Series, we offer the industry’s broadest range of advanced drives for control of rotary servomotors and linear positioning systems, with the connectivity options, power ranges and features to handle any application.

Electric cylinders from Kollmorgen offer strong thrust, high speed and exceptional positioning accuracy. Designed to provide a clean, efficient replacement for hydraulic actuators and pneumatic cylinders, these high-precision, closed-loop systems have rapidly become the preferred alternative for many linear applications.

The N2 Series offers an economical, light-duty design with a small package size. Durable and easy to use, these electric cylinders provide simple extend-and-retract motion, with the ability to position either to predetermined stop locations or to an analog voltage input.

The EC1 Series offers a limited selection of application solutions designed to reduce cost and minimize cylinder frame size by 30 to 40 percent. The small package design is perfect for converting from pneumatic cylinders in many applications.

EC2 Series electric cylinders are an economical solution for light to moderate thrust loads. With a choice of ball or lead screw designs, these cylinders yield quiet operation, low backlash and high accuracy with a selection of motor-to-screw reduction types.

The EC3 Series provides a robust linear motion package for moderate to heavy thrust loads. They are available with a ball or lead screw and a variety of motor-to-screw reduction ratios, providing exceptionally quiet operation, low backlash and high accuracy.

The EC4 Series is a heavy-duty motion package designed to move heavy thrust loads with superior precision and minimal backlash. This series features precision-rolled ball screws with a selection of motor-to-screw reduction ratios.

For the heaviest thrust loads, our EC5 Series offers an extremely robust design with precision-rolled ball screws available with a selection of motor-to-screw reduction ratios. Like all our electric cylinders, they provide exceptional accuracy, low backlash and quiet operation.

Rodless Actuators
R2A Series
R3 Series
R4 Series

Instead of the moving rod of an electric cylinder, these rodless actuators feature a moving carriage supported by linear bearings within an extruded aluminum chassis. This design enables the rodless actuator to guide and support the load being positioned.

The R2A Series offers a carriage bearing design that produces lower bearing friction, smoother operation and zero running clearance. A flexible seal prevents environmental contamination and ensures long life, making the R2A Series an effective solution for industrial-grade requirements.

R3 Series rodless actuators provide a robust design with an internal linear motion guide rail and built-in flexible seal to ensure reliable operation in industrial environments. Equipped for high loads or high acceleration with maximum duty cycle, the R3 Series is available with either belt drive for the most rapid moves or screw drive for the highest thrust capacity and repeatability.

The R4 Series is our most powerful rodless actuator, designed to quickly accelerate, accurately position and reliably support the heaviest loads. An internal linear motion guide rail with a built-in flexible seal withstands maximum duty cycle in harsh industrial environments.

Precision Tables
DS4/6 Series

Precision tables are best suited for applications where accuracy and repeatability are more important than axial thrust. They can also be used in applications that require substantial moment load support, and they’re ideal building blocks for multi-axis positioning systems.

DS Series precision tables provide outstanding performance, with the configuration flexibility to suit almost any single-or multi-axis application. Our proven magnetic stainless steel seal strip effectively seals the internal components from contaminants for durable performance in demanding industrial settings.

All our gearheads incorporate True Planetary gearing for high torque capacity, smooth operation and minimal maintenance. So you can count on optimum performance, whether you need a general-purpose gearhead, an ultra-precise model, a washdown or food-grade version, or a complete gearmotor.

The DuraTRUE™ Series offers high-precision gearheads with a variety of shaft configurations, allowing you to design your system in the smallest of envelopes by eliminating the need for couplings. You can even run two axes with one motor using the DuraTRUE “T” design.

For continuous duty cycle applications, our EverTRUE™ Series gearheads are lubricated for life and rated for at least 30,000 hours of 24/7 operation. These high-precision gearheads are compatible with our RediMount mounting system for easy installation on almost any motor.

NemaTRUE™ gearheads are available in four standard NEMA sizes, three metric sizes, and both in-line and right-angle versions—all featuring our RediMount mounting system. These precision gearheads provide a versatile and economical solution for many applications..

Right-angle bevel gear meshes are typically limited to ratios from 1:1 to 3:1. Our PowerTRUE™ 90 gear technology uses an advanced tooth design to increase the ratio range to 5:1. It’s available on NemaTRUE, DuraTRUE, UltraTRUE and ValueTRUE 90° gearheads.

The RediMount™ motor mounting system allows mounting of our TRUE Planetary gearheads to practically any motor available on the market. The innovative design, featuring an adapter sleeve and input housing, ensures that gearhead mounting Is always quick, easy and error-free.

The UltraTRUE™ Series combines our highest-precision helical crowned gearing with TRUE Planetary orientation to create the smoothest and quietest gearheads on the market today. A wide range of metric frame sizes and gear ratios are available in straight and 90° versions.

Our ValueTRUE™ Series delivers high precision at a competitive price. With only 4 arc-minutes of backlash, and available in a wide range of frame sizes and ratios, they’re perfect as original equipment or as a drop-in replacement for most common helical gearheads.
