1 Integrated Hybrid Servo Motors vs. Standard Integrated Servo Motors (December 2018)

Different motor types favor different application areas. No single style has advantages in all application spaces. Direct drive applications favor hybrid servos while high-speed, geared down applications tend to favor the conventional servo motors.

2 Step vs. Servo - Selecting the Best (October 2018)

Over the many years, there have been many technical papers and articles about which motor is the best. The short and sweet answer is - let's talk about the application. More recently a number of papers and articles have appeared that compared each motor's advantages and disadvantages in generic or specific terms. Many times, the methods used to drive and control these motors are not completely described due to the many control schemes available for use. A few articles focus on just the open loop step motor and the closed loop servo motor advantages and disadvantages in a laundry list format. This article is attempting to "drill down" into the reasons why and to describe how it is done.

3 Gearbox Innovation Evolves in Step with Expanding Servo Market (September 2018)

Approximately one quarter of all servo motors around the world require some type of gear reduction in their applications. From large satellite dishes to precision medical devices, gearboxes boost torque and reduce speed for servos in order for them to be sized more efficiently. While gearbox fundamentals haven't changed much over the past 20 years, their effectiveness has improved significantly, driven mostly by the need to accommodate advancements in servo technology.

4 The Clean Cut (August 2018)

JBT Corporation benefits from Kollmorgen Hygienic motor design in food and beverage application.

5 Development of an Actuator for Ambient to Cryo Application (December 2010)

During the qualification campaign of the NIRSpec (near-infrared spectrometer) instrument mechanism, the actuator could not achieve the expected lifetime that had been extended during the development phase. The initial design could not be adapted to the requested number of revolutions during that phase. Consequently the actuator needed to be modified so that the function of the mechanism would not be endangered or, by extension, the overall function of the NIRSpec instrument. The modification included a change of the overall actuator design—internal dimensions, tolerances, materials, lubrication and assembly process—while keeping the interface to the mechanism, mass and function.

6 Smart Actuators for Off-Highway (February 2013)

Smart actuators bring big benefits to utility and other off-highway vehicles

7 Realizing the High Precision Load Handling Benefits of Rodless Electromechanical Actuators (February 2019)

Electromechanical rodless linear actuators can offer better load handling in smaller spaces than rod-style actuators, but realizing those benefits requires careful attention at the specification level. Whether you are replacing a failed actuator, looking for better performance or building a new application from the ground up, success depends on how precisely you specify application requirements.

8 Efficiency of Design (February 2018)

Energy efficiency is for more than just motors. Here are some mechatronics companies making sure you get more bang for your buck when it comes to your power bill.

9 Space Shuttle Rudder-Speed Brake Actuator (October 2015)

The U.S. Space Shuttle fleet was originally intended to have a life of 100 flights for each vehicle, lasting over a 10-year period, with minimal scheduled maintenance or inspection. The first space shuttle flight was that of the Space Shuttle Columbia (OV-102), launched April 12, 1981. The disaster that destroyed Columbia occurred on its 28th flight, February 1, 2003, nearly 22 years after its first launch.
