Alxion

ALXION has been established in 1987 with the challenge to design and manufacture precise and compact servomotors dedicated to direct drive without gear of automated industrial axis.
ALXION is an undisputed leader in High Torque Permanent Magnet Motors for Factory Automation and Alternators for Wind and Water Turbines operating in Direct Drive without gear.

Alxion Servo Drives

System overview

• Highly compact, modular design for top productivity

• the DS2020 is the new digital “stand-alone” servodrive, purposely designed with reduced dimensions.
The current sizes of the four versions (50, 75, 85 and 125 mm) range from 2 Arms to 48 Arms continuous, and from 4 Arms to 96 Arms peak.

• Designed to work with different motor types and feedback devices
The DS2020 servodrive is designed to control synchronous brushless or asynchronous motors (it is compatible with various feedback systems (Resolver, HIPERFACE single and multi-turn encoders, ENDAT encoders, incremental encoders) as well as motors with sensorless algorithms.

• User-friendly graphic user interface (GUI)
The graphic user interface offers easy access to all the functions, simplifying the settings, initial startup and system monitoring. Communication with the PC is via a USB or RS422 interface.

• Integrated Safe Torque Off (STO) function
The Safe Torque Off safety function is integrated as standard in every servodrive

Applications

• Single-axis applications in industrial automation

• Applications with high precision and top dynamics

• Applications requiring significant space saving during installation

• Applications with personalised functions and flexible configurations

• Applications requiring quick, precise movements

DS2020 Single Axis
Extremely Compact Servo Drives

Extremely Compact electronic Servo Amplifiers for motion control of PM brushless motors in particular torque motors in single axis applications as handling, pick and place, test benches, rotary tables, winders and unwinders for powers up to  30 KW continuous and 60 KW peak.
