KTR has developed a steel lamina coupling for servo drives in the higher power range. The backlash-free and torsionally rigid RADEX-NC High Torque covers speeds up to 27,500 rpm while transmitting torques up to 2,000 Nm. Main application ranges are machine tools as well as measuring and test bench technology. KTR will introduce the coupling […]

Servo couplings: Stiffness, damping, hunting, and stabilization considerations
Here we address considerations when specifying servo couplings to satisfy servo requirements — ever-evolving specifications that become more demanding all the time. By Tetsuya Niwa • Director of product planning and development Kei Yamada • Product Manager — Product planning and development Hiroki Goto • engineering specialist Paulo Castelo • Technical solutions supervisor • NBK America […]
Damping servomotor couplings — New ways to use flexible couplings to minimize hunting and boost system stability
August 27, 2017 update: The full-length technical feature on this servo-coupling topic of damping and gain setting is now live. New technological improvements in servomotors have spurred dramatic improvements in response frequencies. The catch is that vibration (and hunting) tend to arise when designers apply high gain settings to servo systems and use advanced couplings […]
Backlash-free servo couplings for all drive constellations
mayr power transmission provides a wide spectrum of backlash-free, high-performance servo couplings and is permanently expanding its standard modular system. Furthermore, new, modern production processes ensure favourable prices and short delivery times. In addition, the company also stands for diverse, future-orientated solutions for safety brakes and overload clutches. For customers, this means high-quality power transmission […]
What is electrical isolation?
What is electrical isolation? Electrical isolation is used to separate drive and driven components to prevent extraneous electrical currents from being passed between them. Specifying the wrong coupling or not understanding how a specific coupling fails can lead to electrical currents inadvertently being passed between components. You see electrical isolation in mostly encoder and instrumentation applications […]
High-gain rubber couplings from NBK
NBK America now offers the XG Series of couplings. Why? TO keep pace with the evolution of servomotors. Couplings today are a key component for helping servomotor-driven setups deliver speed-response frequencies … without the problem of vibration that usually accompanies such designs. In fact, it’s difficult to get maximum servomotor performance with high-rigidity couplings such as […]

Couplings for medical equipment provide zero backlash and high torsional stiffness
Medical systems require components that are made to exacting and consistent standards. The ServoClass Couplings will not only perform to the technical levels specified, but they will also be highly consistent and repeatable in every dimension, tolerance, and material specification. ServoClass couplings are a suitable coupling for the precise positioning requirements in today’s demanding medical […]
