The SFD-M high-resolution encoder provides multi-turn absolute suggestions. | Supply: Kollmorgen
Kollmorgen Corp., a developer of movement management and automation programs, this week launched the Good Suggestions System, Multi-Flip, or SFD-M, encoder. It mentioned 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 supplies multi-turn absolute performance with distinctive place accuracy and determination at zero extra value 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 a whole lot of {dollars} per motor and probably 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 complete 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 programs.”
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 higher 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 car (AGV) management programs, and automation management platforms. The Radford, Va.-based firm mentioned its know-how combines efficiency, reliability, and ease of use to provide machine builders a market benefit.

SFD-M supplies 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, 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 essential when exact monitoring of place is required over massive rotational distances, resembling in machine software positioning, packaging machines, materials dealing with, satellite tv for pc monitoring, and lots of different functions, mentioned 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 mentioned.
Kollmorgen shares key specs
Absolute multi-turn encoders from different suppliers typically require a battery to retain positioning info when the system is powered down or throughout an influence failure, famous Kollmorgen. These exterior batteries require substitute and could be topic to failure. Different 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 sources and reduce waste.
Kollmorgen mentioned the SFD-M is very 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
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 Could 1 on the Boston Conference and Exhibition Heart. The corporate will probably be exhibiting at Sales space 644.
As well as, on Thursday at 2:30 PM, Stephen Funk, an electromagnetics design engineer knowledgeable at Kollmorgen, will probably be talk about “How one can Choose the Proper Motor to Cut back Value and Time to Market.”
His presentation will discover the stability between configuration and customization. Funk will have a look at the continuum from normal and configurable merchandise, which provide fast options, to customization, which supplies the flexibleness wanted for exact optimization. That is notably essential in tailoring motor properties to satisfy stringent necessities, providing a definite benefit in robotic functions, in accordance with Funk.
The Robotics Summit additionally provides quite a few networking alternatives, a Profession Honest, a robotics improvement problem, the RBR50 Robotics Innovation Awards Gala, and extra.
