What's the best way to achieve high torque and smooth operation at relatively low speeds, as required for EO/IR applications? Read our blog to find out.

Brushless motors dominate the market, and with good reason.  Learn the design principles, benefits and best uses for both motor types in our new blog.

There’s a lot of fog in the market surrounding cogging torque, its effect on torque ripple, and how to achieve the smoothest motion for EO/IR imaging. Let Kollmorgen's experts clear it up.

What is the best motor technology to use in a motion control application? There are numerous technologies to create motion, from hydraulic to pneumatic or electromechanical. In the world of precision motion control, many machine designers face a choice between step motor or servo motor technologies to solve their performance requirements. Both stepper motors and servo motors have a place in the motion control world but understanding when to use each has created a big debate

From the surface of Mars to the depths of the ocean, from the core of the earth to the core of the human body, Kollmorgen motion systems take on the most extreme environments.

Bode plots have existed since the 1930’s when Hendrik Bode devised a way to display gain and phase-shift plots in the frequency domain. Today, to produce a detailed frequency response plot that reveals the unique fingerprint of a servo mechanism in the frequency domain is as simple as pressing a computer key. This paper discusses five key items in a Bode plot and what they reveal about the machine.

A servo motor is an electromechanical device that produces torque and velocity based on the supplied current and voltage. A servo motor works as part of a closed loop system providing torque and velocity as commanded from a servo controller utilizing a feedback device to close the loop. The feedback device supplies information such as current, velocity, or position to the servo controller, which adjusts the motor action depending on the commanded parameters.

We’ve all seen the movies…the one where the ‘intelligent’ robots go off-piste and bring untold chaos to the human race.  It never really turns out rosy just as the end credit start to fall. However, regardless of Hollywood’s ‘predictions’, no matter where I go or where I look (as part of my role in Kollmorgen’s Aerospace & Defence team) I am constantly tripping over a growing exposure to robotics and Intelligent robots in the Defence sector; air, land, sea and subsea.

Who you are defines how you think of robotics and automation.  Software experts and IT may think of internet bots.  They might also think about the new, emerging field of Robotics Process Automation (RPA), which is software that can do mundane and administrative computer tasks.  RPA reduces repetitive tasks such as checking, verifying and transferring data.  Manufacturing facilities will think about physical robots or cobots that are also deployed to handle repetitive tasks such as loading and unloading a CNC machine or installing a computer cover.  They can also be used to automate dangerous tasks such as lifting, welding or removing paint.

Frameless, or “servo motor kits”, open up numerous possibilities in designing motion elements for your machine related to performance.  A frameless motor consists of rotor and stator components which are built into a machine assembly to transmit torque to a load.  Many applications which take advantage of a frameless motor are direct driven, which eliminates bandwidth robbing compliance.  Effectively, this means you have eliminated torsional losses and any wind-up or spring losses.
