Complete servo systems for precise motion control

A servo system is a closed-loop motion control solution that continuously compares the commanded motion with real feedback from the motor or load. This allows the system to correct position, speed and torque in real time. Compared with simple motor control, servo technology provides higher accuracy, faster dynamic response and better stability under changing load conditions.

A complete servo axis normally includes a servo motor, servo drive, feedback device, cables and a control system. In more advanced machines, several servo axes may be synchronized through industrial communication networks such as EtherCAT, PROFINET, EtherNet/IP, CANopen or other motion-control architectures.

What does a servo system include?

• Servo motor – generates precise rotary motion with feedback for position, speed or torque control.
• Servo drive – controls the motor current, speed and position according to the machine command.
• Feedback device – encoder, resolver or smart feedback system that provides real-time position information.
• Motion controller or PLC – coordinates one or multiple axes and communicates with the machine control system.
• Cables and accessories – power, feedback, hybrid cables, brakes, connectors and mounting accessories.

Why choose Kollmorgen servo systems?

Kollmorgen is a global motion-control manufacturer offering servo motors, servo drives, automation platforms and complete motion solutions for industrial machines. Its product range covers standard servo axes, high-performance motion systems, compact machine designs and specialized applications where precision, reliability and dynamic performance are critical.

Kollmorgen servo drives are designed to provide precise control, strong torque performance, advanced connectivity and compact packaging for applications where position, speed or torque control is important. This makes them suitable for OEM machine builders, system integrators and industrial modernization projects.

How to select the right servo system

Correct servo system selection should start from the real machine requirement, not only from the motor power rating. Important parameters include load inertia, required speed, continuous and peak torque, acceleration, duty cycle, mechanical transmission, feedback type, braking needs, supply voltage, communication protocol and environmental conditions.

A common mistake is selecting a system that is either too weak for the load or unnecessarily oversized for the application. Both cases can create problems: insufficient performance, higher cost, difficult tuning, excessive heat or unstable machine behavior. A balanced motor and drive combination helps achieve better performance, reliability and cost efficiency.

Typical applications

Servo systems are used in machines where motion must be accurate, synchronized and repeatable. They are especially important in applications with fast acceleration, variable loads, coordinated axes or strict positioning requirements.

• Packaging and filling machines;
• Robotics and handling systems;
• CNC machines and cutting equipment;
• Automated assembly lines;
• Conveying and indexing systems;
• Printing, labeling and converting machines;
• Medical, laboratory and test equipment;
• Special-purpose OEM machines.
