The SFD-M high-resolution encoder gives multi-turn absolute suggestions. | Supply: Kollmorgen
Kollmorgen Corp., a developer of movement management and automation methods, this week launched the Good Suggestions Machine, Multi-Flip, or SFD-M, encoder. It stated the SFD-M permits machine builders to realize high-resolution, multi-turn suggestions with absolute positioning info accessible at system startup.
“Our new SFD-M encoder gives multi-turn absolute performance with distinctive place accuracy and backbone at zero extra price over Kollmorgen motors with single-turn encoders,” stated Chris Cooper, senior director of worldwide 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 expertise with auto drive setup additional lowers whole prices. We’re very proud to supply all of those advantages to our clients 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 allows it to offer multi-turn efficiency, 4 instances higher positioning accuracy, and 50 instances decrease EMF noise.
Kollmorgen has greater than 100 years of movement expertise. Its intensive product portfolio contains motors, drives, linear actuators, automated guided automobile (AGV) management methods, and automation management platforms. The Radford, Va.-based firm stated its expertise combines efficiency, reliability, and ease of use to present machine builders a market benefit.

SFD-M gives absolute multi-turn positioning
Kollmorgen stated the SFD-M is equal to different third-party encoders that include a premium value. With the SFD-M, clients 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 course.
This absolute multi-turn positioning functionality is necessary when exact monitoring of place is required over massive rotational distances, reminiscent of in machine instrument positioning, packaging machines, materials dealing with, satellite tv for pc monitoring, and plenty of different purposes, stated Kollmorgen.
The SFD-M additionally maintains absolute positioning info in actual time, even when the system is powered down, eliminating the necessity for time-consuming homing sequences upon startup, the corporate stated.
Kollmorgen shares key specs
Absolute multi-turn encoders from different suppliers usually require a battery to retain positioning info 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 options use mechanical gear trains, that are noisy, backlash-prone, and add measurement to the motor.
The brand new Kollmorgen SFD-M eliminates these points, as an alternative utilizing energy-harvesting expertise to reliably preserve positioning info without having for batteries or gear trains. Battery-free operation eliminates upkeep points whereas additionally supporting efforts to scale back the consumption of pure sources and decrease waste.
Kollmorgen stated 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 rely
- 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 & Expo, which takes place April 30 to Might 1 on the Boston Conference and Exhibition Heart. The corporate will likely be exhibiting at Sales space 644.
As well as, on Thursday at 2:30 PM, Stephen Funk, an electromagnetics design engineer skilled at Kollmorgen, will likely be discuss “How one can Choose the Proper Motor to Cut back Price and Time to Market.”
His presentation will discover the steadiness between configuration and customization. Funk will take a look at the continuum from normal and configurable merchandise, which provide fast options, to customization, which gives the pliability wanted for exact optimization. That is notably necessary in tailoring motor properties to satisfy stringent necessities, providing a definite benefit in robotic purposes, based on Funk.
The Robotics Summit additionally gives quite a few networking alternatives, a Profession Truthful, a robotics growth problem, the RBR50 Robotics Innovation Awards Gala, and extra.
