Kollmorgen Corp., a developer of movement management and automation programs, 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 backbone 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 bunch of {dollars} per motor and probably a number of thousand {dollars} in a posh, 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 programs.”
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 larger 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 programs, 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 offers absolute multi-turn positioning
Kollmorgen stated 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 full 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 giant rotational distances, akin to in machine device positioning, packaging machines, materials dealing with, satellite tv for pc monitoring, and plenty of different functions, 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 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 might be topic to failure. Different alternate 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 a substitute utilizing energy-harvesting expertise to reliably keep 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 probably be exhibiting at Sales space 644.
As well as, on Thursday at 2:30 PM, Stephen Funk, an electromagnetics design engineer professional at Kollmorgen, will probably be talk about “The way to Choose the Proper Motor to Scale back Price and Time to Market.”
His presentation will discover the steadiness between configuration and customization. Funk will have a look at the continuum from commonplace and configurable merchandise, which supply fast options, to customization, which offers the pliability wanted for exact optimization. That is significantly essential in tailoring motor properties to fulfill stringent necessities, providing a definite benefit in robotic functions, in line with Funk.
The Robotics Summit additionally gives quite a few networking alternatives, a Profession Honest, a robotics improvement problem, the RBR50 Robotics Innovation Awards Gala, and extra.
