In servo systems, optimising performance factors such as gain and phase shift is critical to achieving precise control. While modern microprocessors can tune servo drives and motors to balance control attributes, using the traditional approach to understand servo system behaviour across frequencies can be vital. The Bode Plot enables fine tuning of complex servo systems and it can also enhance diagnostics.

Kollmorgen has enhanced its AKM and AKM2G servo motor families with a new high-resolution encoder option that provides absolute multi-turn feedback — at no additional cost compared to the existing absolute single-turn variant. The Kollmorgen SFD-M encoder option achieves four times greater positioning accuracy than previous designs. The encoder tracks and maintains the position register even after power off, thanks to an innovative battery-free design.

Requiring compact, low weight, and torque-dense motion systems, exoskeleton designers continue to see the advantages of frameless brushless DC (BLDC) motors with harmonic gearing. Particularly for complex, multi-jointed exoskeleton applications, engaging the right support in motion development from the outset can save significant project development time.

For all but the very highest force requirements, electric servo presses provide numerous advantages over their historic, hydraulic counterparts. The actuator is integral to press capability, as well as production quality, and levels of productivity, making its specification central to electric servo press design.

For a range of applications, from blood analysers through to semiconductor capital equipment, automated microscopes achieve image gathering that is both faster and significantly more accurate. To optimise the clarity and detail of image capture, an automated microscope’s motion control architecture must synchronise an XYZ axis system with optimum precision.

Robotics and automation have the potential to transform farming to a more productive and efficient model. Servo motors will be vital to power this equipment, providing high levels of precision control. However, these motors will face the rigours of the farm environment, including adverse weather, corrosive substances, as well as the challenge of a regular washdown. To reliably power smart agricultural machinery, servo motors must be built to last.
