Kollmorgen Servo System Product Guide

Subverting tradition: Direct Drive Technology (DDT) - achieving ultimate accuracy and dynamic response

In order to overcome the precision, bandwidth, and maintenance bottlenecks caused by traditional mechanical transmissions (gearboxes, belts, couplings, etc.), Colemorgen provides a comprehensive direct drive solution.

1. Directly drive the rotating motor:

Kohlmorgen's direct drive rotary motors are divided into three categories: Cartridge DDR, Housed DDR, and Frameless DDR, which meet different integration requirements.

Cartridge DDR: Revolutionary combination of the space saving advantages of frameless motors and the easy installation features of framed motors. It uses the machine's own bearings to support the rotor and connects the load through an innovative compression coupling. Its torque density can be 50% higher than traditional servo motors of the same size, and it integrates a high-resolution sine encoder (134217728 counts/rev) with a repeatability accuracy of better than 1 arcsecond and an absolute accuracy of ± 26 arcseconds, far superior to precision planetary gearboxes (usually with 1-2 arcminutes backlash). In applications such as feeders, it replaces the motor+reducer+belt drive system, reducing assembly time from hours to 5 minutes, significantly reducing the number of parts, increasing throughput by up to 100%, and achieving zero maintenance.

Housed DDR: Comes with bearings and encoders to form a complete rotating component, making it ideal as the core drive for turntables or indexing plates. Its high stiffness, zero backlash, and excellent dynamic performance make it outstanding in medical manufacturing and semiconductor equipment, significantly reducing audible noise and supporting flexible electronic cam and electronic gear functions.

2. Directly drive linear motor:

Directly driving a linear motor eliminates intermediate transmission links such as ball screws and gear racks, and applies power directly to the load. This brings infinite travel possibilities, zero backlash, ultra-high acceleration, extremely smooth speed control, and almost zero maintenance requirements. Colemorgen offers hundreds of customized and semi customized linear motor solutions, with a thrust of up to 15.6 kN and precision of micrometer level, making it an ideal choice for high-speed and high-precision laser processing, electronic assembly, and testing equipment.

Precision Transmission and Positioning: Modular Mechanical Components

For applications that still require mechanical transmission, Colemorgen offers a range of high-performance, modular positioning and transmission components.

1. Precision positioning table (DS4/DS6 series):

The DS series positioning station is an ideal module for building high-precision single axis or multi axis (XY, XYZ) systems. They use high-quality ball screws, linear guides, and unique IDEAL-SEAL magnetic seal technology to effectively protect the internal structure. We offer two precision levels: commercial grade and precision grade, with a bidirectional repeat positioning accuracy of ± 1.3 microns (precision grade). Rich options, such as motor installation direction (direct or parallel), coupling type, limit/origin sensor, and linear grating ruler, allow users to deeply customize.

2. Electric cylinder and rodless actuator:

Electric cylinder (N2/EC series): As a clean and efficient alternative to hydraulic and pneumatic cylinders, electric cylinders provide precise thrust control and position control. The EC series complies with the ISO 6431 standard, with a thrust range from 667 N to 25000 N and a maximum speed of 1.33 m/s. It comes standard with IP54 protection (optional IP65). They are suitable for linear pressing, lifting, and valve control applications that require high thrust.

Rod free actuator (R series): Integrated with linear bearings, it can provide thrust while supporting and guiding loads. The R series offers options for ball screw, lead screw, or synchronous belt transmission, with a travel of up to 2.7 meters and a maximum speed of 3 m/s (with transmission). Its compact cross-sectional design makes it an efficient component for building Cartesian coordinate robots.

3. Micron ™  TRUE Planetary ™ Reducer:

Using unique spiral crown gear technology, compared to traditional spur gear planetary reducers, it has a higher contact ratio, bringing higher torque capacity, better load sharing, lower backlash (up to 4 arcminutes), and almost "whisper" level quiet operation. RediMount ™ The system simplifies the installation and docking with servo motors, ensuring error free assembly. In addition, PowerTrue is used ™ The right angle reducer with face gear technology achieves a single-stage transmission ratio of up to 5:1 and an efficiency of 98%, with a very compact structure.

From Components to Systems: Integrated Control and Customized Solutions

The core competitiveness of Colemorgen lies in its ability to provide solutions rather than just system integration of components.

1. Kollmorgen Automation Suite ™：

This is a unified and scalable automation development kit that covers programming, configuration, and debugging from single axis drives to PAC based 128 axis complex motion control systems. It supports all five IEC 61131-3 programming languages (including ladder diagrams, structured text, etc.) as well as PLCopen motion control function blocks. Its innovative Pipe Network ™  The programming approach allows engineers to describe complex multi axis coordinated movements (such as electronic camshafts and flying shears) in intuitive data flow form, greatly simplifying the development of advanced applications.
