The compact LTM-CI from STIWA is optimized for small half meeting. | Supply: FAULHABER
STIWA is an skilled developer of compact mechatronic techniques that may carry out a sequence of consecutive product steps autonomously. The Austrian machine producer mentioned its LTM-CI is optimized for small components meeting.
Compact automation may be important for finish customers that wish to automate however don’t have the area for a big system. As well as, these compact techniques can excel at dealing with small parts. STIWA designed its system for merchandise with a spatial diagonal of as much as 30 mm (1.1 in.).
“A buyer within the west of Austria produces dampers for a well known furnishings retailer that wants tens of millions of those components yearly,” mentioned Roland Schiermayr, head of the Automation Analysis and Improvement Division at STIWA.
“The corporate needed to purchase a brand new manufacturing machine,” he mentioned. “The prevailing machine was 10 m [32.8 ft.] lengthy – for the manufacturing of small parts measuring just some centimeters in size, this was merely an excessive amount of for the manufacturing website in a slender Alpine valley. This was the impetus for us to totally make the most of all miniaturization prospects.”
For its compact automation techniques, the firm makes use of linear and rotating micromotors from FAULHABER to carry out key duties.

Contained in the LTM-CI
Automated actions throughout the LTM-CI occur so shortly that the human eye can barely sustain with the person automation steps. First, the system feeds particular person components from storage containers and separates them utilizing a shaker. It then appropriately positions these components on a conveyor belt so it’s prepared for the following manufacturing step.
Subsequent, the system transports the parts to the respective stations. There, delicate grippers decide them up and be part of them collectively, or course of them another way. STIWA compares the actions of the system to a dance, combining the graceful transport of conveyor belts with the fast actions of grippers.
This whole system, relying on the configuration and tools wanted, is simply 3 to 4 m (9.8 to 13.1 ft.) lengthy. STIWA made the bases of the system from a rigidly linked transport system, and the opposite system parts rely on the wants and specs of the shopper.
“We will combine as much as 22 operate modules, every measuring 90 mm [3.5 in.] in width, for various work steps,” mentioned Christian Mersnik, who was concerned in growth from Day 1. “These features embody, for instance, decide and place, laser welding with as much as 5 levels of freedom, screw insertion, press-in operations, labeling, in addition to testing and measuring processes.”
STIWA compact automation will get buyer curiosity
STIWA mentioned that its compact automation system has been nicely acquired by clients. Its clients respect the uniform, clean actions of the system. In addition they say that these actions don’t include impacts or vibrations, which ensures a steady course of.

The corporate mentioned the LTM-CI can cut back cycle occasions to nearly simply half a second, which brings a major leap in productiveness. STIWA famous that the drives used within the FAULHABER actuators make a serious contribution to the graceful motion of the machine and its excessive pace.
The LTM-CI makes use of the LM 1247 linear actuator motor from FAULHABER. This actuator performs its process at as much as 20 factors within the system, together with stopper models and grippers. STIWA claimed that one specific energy of the FAULHABER linear motors is its excessive pace. At simply 12.5 mm (0.4 in.) broad and 19.1 mm (0.7 in.) excessive, the drive can produce a steady power of three.6 Newtons.
The system additionally makes use of FAULHABER’s brushless BX4 2250 sequence of motors. Within the portal dealing with of the compact automation, this motor drives the swivel models that transfer the instruments or parts to a selected place.
“At this level within the system, we require an especially excessive stage of precision and repeatability,” Mersnik mentioned. “For this reason it was an vital argument for us that FAULHABER was capable of ship this motor with an identical multiturn absolute encoder. The indicators from this encoder are essential to realize the excessive manufacturing high quality and for high quality assurance.”
STIWA ensures its compact automation clients fault-free operation of at least 60 million strokes. This quantity must be achieved by all of the shifting components throughout the system, which is another excuse why the corporate picked FAULHABER as its companion.
“We topic our personal components in addition to moreover bought parts to endurance exams,” Schiermayr mentioned. “In these exams, we try and destroy the components by put on and unfavorable situations. Solely these components that survive the endurance exams are put in within the machines.”
“The motors from FAULHABER have proven that they’ll meet such excessive necessities,” he added. “They assist us to realize our personal peak values with minimal area necessities and the shortest cycle occasions.”
