The SFD-M high-resolution encoder affords multi-turn absolute suggestions. | Supply: Kollmorgen
Kollmorgen Corp., a developer of movement management and automation techniques, this week launched the Good Suggestions Gadget, Multi-Flip, or SFD-M, encoder. It stated the SFD-M permits machine builders to attain high-resolution, multi-turn suggestions with absolute positioning info obtainable at system startup.
“Our new SFD-M encoder offers multi-turn absolute performance with distinctive place accuracy and determination at zero extra value over Kollmorgen motors with single-turn encoders,” stated Chris Cooper, senior director of world product administration at Kollmorgen.
“That’s an enormous profit for precision and productiveness at a financial savings of a whole lot of {dollars} per motor and doubtlessly a number of thousand {dollars} in a posh, 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 techniques.”
Designed to work with AKD and AKD2G drives, the SFD-M absolute multi-turn encoder could 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 occasions larger positioning accuracy, and 50 occasions 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 techniques, and automation management platforms. The Radford, Va.-based firm stated its know-how combines efficiency, reliability, and ease of use to provide machine builders a market benefit.

SFD-M offers 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, 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 whole variety of rotations the shaft has made in both path.
This absolute multi-turn positioning functionality is essential when exact monitoring of place is required over massive rotational distances, resembling 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 could 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 a substitute utilizing energy-harvesting know-how to reliably preserve positioning info 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 reduce 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 study extra about Kollmorgen’s newest merchandise, see it on the 2025 Robotics Summit & Expo, which takes place April 30 to Could 1 on the Boston Conference and Exhibition Middle. 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 “Learn how to Choose the Proper Motor to Cut back Value and Time to Market.”
His presentation will discover the steadiness between configuration and customization. Funk will have a look at the continuum from customary and configurable merchandise, which provide fast options, to customization, which offers the flexibleness wanted for exact optimization. That is notably essential in tailoring motor properties to satisfy stringent necessities, providing a definite benefit in robotic purposes, based on Funk.
The Robotics Summit additionally affords quite a few networking alternatives, a Profession Honest, a robotics improvement problem, the RBR50 Robotics Innovation Awards Gala, and extra.
