Kollmorgen Announces TBM2G Motor Series

April 21, 2022

Kollmorgen has announced the new TBM2G series of frameless servomotors, introducing features that simplify the design of collaborative, surgical, aerospace and defense and other robots while delivering optimal performance in a lighter, more compact package. These new motors will complement Kollmorgen’s existing TBM and KBM series of frameless motors.

Closing the Loop around a Transverse Flux Hybrid Step Motor

August 1, 2020

Transverse magnetic flux motors -- also known as step motors -- become Hybrid Servos when you operate them closed loop. This is the same transformation that happens between running a 3-phase synchronous motor from line voltage as opposed to running it closed loop as a brushless servo. In the case of hybrid motors, there are many degrees of what is advertised as "closed loop," and thus significant differences in the performance improvements seen.

Integrated Hybrid Servo Motors vs. Standard Integrated Servo Motors

December 1, 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.

Step vs. Servo - Selecting the Best

October 1, 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.

Servo Motor Performance at Stepper Motor Prices

April 1, 2015

Enhancing production with — and for — less is the standing order in today’s manufacturing world. Speeding up production while at the same time looking for ways, to cut, for example, energy costs, is a tricky equation with no single answer; where and how management goes about achieving that can take several paths.
