The SFD-M high-resolution encoder presents multi-turn absolute suggestions. | Supply: Kollmorgen
Kollmorgen Corp., a developer of movement management and automation methods, this week launched the Sensible Suggestions Gadget, Multi-Flip, or SFD-M, encoder. It mentioned the SFD-M permits machine builders to attain high-resolution, multi-turn suggestions with absolute positioning data obtainable at system startup.
“Our new SFD-M encoder gives multi-turn absolute performance with distinctive place accuracy and determination at zero extra price over Kollmorgen motors with single-turn encoders,” mentioned Chris Cooper, senior director of world product administration at Kollmorgen.
“That’s an enormous profit for precision and productiveness at a financial savings of tons of of {dollars} per motor and doubtlessly a number of thousand {dollars} in a fancy, multi-axis machine,” he added. “Single motor-to-drive cable know-how with auto drive setup additional lowers whole prices. We’re very proud to supply all of those advantages to our prospects as an integral a part of Kollmorgen’s industry-leading servo methods.”
Designed to work with AKD and AKD2G drives, the SFD-M absolute multi-turn encoder might be built-in into Kollmorgen-housed servo motors. This comes at no extra cost as compared with the SFD-3 single-turn absolute encoder. This permits it to offer multi-turn efficiency, 4 instances better positioning accuracy, and 50 instances decrease EMF noise.
Kollmorgen has greater than 100 years of movement expertise. Its intensive product portfolio consists of motors, drives, linear actuators, automated guided car (AGV) management methods, and automation management platforms. The Radford, Va.-based firm mentioned its know-how combines efficiency, reliability, and ease of use to offer machine builders a market benefit.

SFD-M gives absolute multi-turn positioning
Kollmorgen mentioned the SFD-M is equal to different third-party encoders that include a premium worth. With the SFD-M, prospects can obtain substantial financial savings in machine designs that carry out at excessive ranges of precision, effectivity, and effectiveness, it asserted.
The SFD-M measures the place of the rotor shaft all through every 360º rotation with out requiring reference to a house place. As well as, it registers the entire variety of rotations the shaft has made in both path.
This absolute multi-turn positioning functionality is vital when exact monitoring of place is required over massive rotational distances, equivalent to in machine instrument positioning, packaging machines, materials dealing with, satellite tv for pc monitoring, and plenty of different purposes, mentioned Kollmorgen.
The SFD-M additionally maintains absolute positioning data in actual time, even when the system is powered down, eliminating the necessity for time-consuming homing sequences upon startup, the corporate mentioned.
Kollmorgen shares key specs
Absolute multi-turn encoders from different suppliers usually require a battery to retain positioning data when the system is powered down or throughout an influence failure, famous Kollmorgen. These exterior batteries require alternative and might be topic to failure. Different alternate options use mechanical gear trains, that are noisy, backlash-prone, and add dimension to the motor.
The brand new Kollmorgen SFD-M eliminates these points, as an alternative utilizing energy-harvesting know-how to reliably preserve positioning data without having for batteries or gear trains. Battery-free operation eliminates upkeep points whereas additionally supporting efforts to cut back the consumption of pure assets and decrease waste.
Kollmorgen mentioned the SFD-M is extremely correct and listed extra specs:
Decision of 24 bits per revolution
16,777,216 counts per revolution
0.0772 arc-sec per depend
Multi-turn absolute vary of 16 bits = 65,536 motor revolutions
Accurcy of < +/– 1 arc-min typical at 25ºC an < +/– 3 arc-min worst case
See Kollmorgen on the Robotics Summit & Expo
To be taught extra about Kollmorgen’s newest merchandise, see it on the 2025 Robotics Summit & Expowhich takes place April 30 to Might 1 on the Boston Conference and Exhibition Heart. The corporate might be exhibiting at Sales space 644.
As well as, on Thursday at 2:30 PM, Stephen Funk, an electromagnetics design engineer professional at Kollmorgen, might be discuss “Learn how to Choose the Proper Motor to Cut back Price and Time to Market.”
His presentation will discover the stability between configuration and customization. Funk will have a look at the continuum from commonplace and configurable merchandise, which supply fast options, to customization, which gives the flexibleness wanted for exact optimization. That is notably vital in tailoring motor properties to satisfy stringent necessities, providing a definite benefit in robotic purposes, in keeping with Funk.
The Robotics Summit additionally presents quite a few networking alternatives, a Profession Truthfula robotics improvement problemthe RBR50 Robotics Innovation Awards Galaand extra.
