Like veins, they come in allshapes and sizes, from the dimensions ofa single strand of hair to several millimeters thick. Schleuniger AG from Thunin Switzerland is geared up to dealingwith this level of variety and offers cleverstripping machines for a wide range ofcable types and diameters. In order toallow precision cutting through‚ thick andthin‘, their machines come with drivesfrom FAULHABER‘S Swiss affiliate MINIMOTOR. The compact micromotors fromthe drive specialists provide the powerrequired to cut through thick insulationas well as the precision needed to exposeeven the finest of wires.Precision and diversityDesigning a stripping machine to meetthe demands of high-end automation engineering applications requires experienceand expertise. The method applied notonly has to consider the format of thedifferent cable types but also the thickness of the conductors to be processed.Depending on user requirements, theSwiss engineering experts can provideprogrammable units for cables from double-insulated cables to coaxial cables.The CoaxStrip 5300 model can handleup to 650 coax ends per hour, depending on the cable type. The UniStrip 2600model can strip off 20 mm of insulationevery 0.6 seconds. The clamping forcecan be motor adjusted in both models.The units come with a list of 1000 cablesor 100 cable lists, so the cable type canquickly be adjusted to suit changes inproduction. Replaceable stripping blades,an insulation extraction system and otherpractical functions allow seamless integration into the existing automation environment.They guarantee many years of troublefree operation. The CoaxStrip 5300 modelalso has a brushless DC-Servomotor forthe constant rotational movement of thecutting unit, which is vital in this application. As this motor has no mechanicalwearing parts apart from the rotor bearing, it is perfect for the continuous operation required. Its service life is in excess of 10,000 hours, so it can meet eventhe exacting demands of three-shiftround-the-clock operation. All DC-Motorsare fitted with built-in encoders. Theseprovide pulses to the controller in thedevice through pre-finished flat ribboncables. There is also a light barrier alignedon each axis to define the start pointand initialize the individual drives. Thisinformation allows the controller to usethe motors to drive the individual axesto the required position precisely andwith a high level of repeat accuracy.www.schleuniger.comCompact drive with encoderThe sophisticated cutting and pullingmechanism in the stripping devicesrequires a drive system that is equallysophisticated. After all, the best knifeonly cuts as accurately as the hand guiding it. This is why the developers optedfor FAULHABER systems. They found theperfect drive system for this applicationfrom the company‘s extensive productrange. Both stripping machines areequipped with three DC-Micromotors.One drive is responsible for clampingthe cables while another moves theblades up and down in the cutting unit.The third member of the team takes careof the controlled removal of the insulating sleeve. As these drives are onlyused for the purpose of adjusting to newcable types or merely for specific tasks,e.g. for the withdrawal movement, usingthem is most cost-effective for diametersfrom 2 to 9 mm upward. The largeroptions can even handle flat ribbon cablesof up to 11 mm in width. Dependingon the area of application, the machinecan remove all or just some of the insulation. Even multiple stripping, stripping ofmains cables with different internal conductor lengths or gradual stripping ofaffordable brush motors is no problem.ISSUE 2 20103
VIDEO & AUDIOOcean filming –tough conditions forcamera and crewM I C R O D R I V E S S TA B I L I Z E C A M E R A S E T- U P D U R I N GOCEAN FILMINGIn the rugged environment of the ocean, making brilliant films iss fafarrfrom easy. To shoot the “OCEANS” documentary, French film companyny“Galatée Films” therefore required some advances to be made to existing camera technology. The challenge of creating the necessary camerastability to ensure shudder-free images could be shot from a permanently shaky surface was a particularly difficult task for the developers. Agyroscopic mounting platform with several DC-Micromotors proved tobe the perfect solution.4Sh ting high-qualityShootingShootihihighh-qualitlity nanatunatureturere ffifilmsiiseven morehard enough on land, butbchallengingsea.chalchallelengnginingg at sseaea.

These requirementsumeant that the 4.5 m-long crane weighing 300 kg had to be able to carry thestabilizing platform with 75 kg of itsown weight, plus camera load. The platform itself can stabilize camera equipment weighing up to 40 kg.Fixed point in spaceAs is the case with aircraft, movementin a boat occurs in all three spatial directions. Lurching, rolling and pitching areoften accompanied by some hard knocks– mechanical impacts that all technicalcomponents must be able to withstand.Shock absorbing mounts can only blockThe performance-inhibiting factors forrapid, dynamic yet precise movements arebreakaway torque, gear backlash anddrive efficiency. The non-linear behaviorof these factors makes it harder for thecomputer to calculate the steering commands. The actual drive consisted of a24 V DC-Micromotor with a 38 mm diameter and matching planetary gearingsupplied by FAULHABER. “The main benefit of the drives”, explains Jacques Perrin,director and co-developer of the stabilizing platform, “lies in their almost cogfree action. They also have no iron lossesand offer high dynamic performancethanks to low rotator inertia. The highperformance ratio is a further plus forour purposes.” The motors weigh aslittle as 400 g but achieve 220 W. Thetriple reduction gearing (with a reductionratio of 1:64) increases the rated torqueto 15 Nm. The maximum torque available in, for instance, emergency situationsis 30 Nm. In order to increase the responseaccuracy and minimize the backlash ofthe gears, two drives work on each axisin a push-pull arrangement. Weighingless than 2 kg, this drive is the optimalsolution due to both its rapid responseand robust construction. The chosenmotor control system is also part of theFAULHABER product range.

This is a serious problem, as high bloodpressure left untreated for many years can trigger a whole series ofsecondary diseases and skyrocketing treatment costs. To ensure optimaldiagnosis and correct medication doses, blood pressure monitoring overa relatively long period of time is essential. A new measuring devicein miniature form facilitates extensive, long-term monitoring, withoutimpeding the day-to-day lives of patients. Modern microdrives insidethe device ensure the necessary mechanical execution of electronic commands.Fluctuating blood pressure or blood pressure that is chronically too high or toolow will at best only impair a person’squality of life. But unfortunately the consequences are usually extensive secondary damage to vital organs like the heartor the kidneys. Conventional electronicmeasuring devices for blood pressuremonitoring only provide snapshot information at the time a single reading istaken, rather than blood pressure profilesover a period of several hours or days. Toaddress this gap, Schiller AG in Baar, Switzerland, has developed a mobile bloodpressure measuring device for long-termblood pressure monitoring. In order tokeep the size of the device as small as possible, the developers went to microdrivespecialist FAULHABER in search of theoptimal drive solution.Everyday convenienceBlood pressure is influenced by a host ofdifferent factors. Any meaningful readingmust therefore take into account normaleveryday activities and be as unobtrusiveas possible. For this reason alone, mobile,6
miniaturized solutions that do not impede patient movement are ideal. Thesolution developed by the Swiss specialistsis based on two key components: sophisticated MT-300 analysis software forsetting and evaluating the measuringsequence and readings, and the BR102plus measuring device itself, completewith sensor and data memory. The lightweight, user-friendly device can be easilyconfigured via PC software. It is equallycapable of storing patient data, statistically analyzing the readings, recordingthe results in the form of patient diariesand many other functions. The actualmeasuring device is suitable for measuring blood pressure over a 24 or 48 hourperiod and offers the choice betweenauscultatoric or oscillometric measuringmethods. This allows even patients withheart rhythm disorders or atrial fibrillation to be monitored. The device canbe easily operated on site, with onlytwo buttons for convenient navigationthrough the menu. Up to four measuringprograms can be saved to the built-inmemory, and there is a special algorithmfor both adults and children. Data can betransmitted from the device via a USBinterface. Despite its compact design, the3 v battery can handle up to 100 readingswhen fully charged. The great versatilityof the device is only possible thanksto precise mechanical execution of theelectronic commands. Miniature components and microdrive technology werethe key to solving this challenge of longterm, non-intrusive monitoring. The experts at Schiller developed a specialpressure regulator for the BR-102plus.An 8-mm drive that mechanically translates the electrical commands ensuressensitive operation of the high-precisioncomponent.controlled torque, it combines with thevalve body and control tube to form asingle unit. This means the overall systemis very lightweight, compact and robust.The special features of this DC-Micromotor from the FAULHABER productrange are crucial to the success of theblood pressure monitor. The preciousmetal commutated drives provide minimal contact resistance on the collector/brush system, allowing them to run onvery low voltage, which is a big advantagefor battery-supported use. The efficiencyratio of over 50 % also enables the device to stay in use for extended periods.Brush wear and tear for short-term usageunder normal conditions is relatively insignificant. What is more important isperfect start-up even after long periodsof inactivity. Maintenance-free bearingswith special lubricants and a preciselybalanced rotor ensure smooth running.To sum up all its attributes, this is a highperformance, long-life, miniaturized drivethat always executes the electroniccommands by the same, reliable process.That is the only way to ensure a series ofreliable readings that provides meaningful and comparable data sets. Modernmicrodrives are the perfect solution formany different applications and all formsof mechanical movements. As a miniaturepower source, they are equally suitablefor dynamic tasks, slow to virtually staticfunctions or pulse-operated processes.www.schiller.chPrecious metal commutatedDC motorThe pressure within the measuring cuff isthe reference point for every measurement.

ROBOTICSMuscular micromotorsM U LT I P L E - A X I S J O I N T M A K E S R O B O T I C A R M L I G H T E RAS IT CAN BE DISCONNECTED FROM THE DRIVEFreely moving arms are a well-established solution when it comes toWe have all seen industrial robot arms:solid constructions for heavy tools – andthey are pretty hefty themselves. In fact,these designs are simply too heavy formany applications. Engineers at igusin Cologne wanted to develop a multipleaxis joint that would allow small loads tobe swiveled or turned around a jib. Theyneeded high levels of flexibility and lowweight, with simple upgrade options foradditional axes. These requirements havenow been elegantly translated into anew concept with a multiple-axis jointmade from plastic and cable controls. Thecables themselves are moved from thearm‘s ”shoulder joint“ using compact,high-performance, brushless DC-Servomotors. This prevents inertia in the arm,allows dynamic movements and meansthe drive block can be compact in design.Bionic approachTo avoid having to reinvent the wheel,the team of engineers looked at furtherrefining the trusted human elbow joint.This allowed two degrees of freedom –rotation and swivel – to be incorporatedin a single joint, thereby guaranteeinghigh levels of precision for the movingparts. The tribo-plastic joint is also maintenance-free and does not corrode orconduct electricity. The “bones“ of thearm to which the joints are attachedare also pared down to a lightweight construction. Aluminum, carbon fiber andfiberglass-reinforced plastic provide excellent rigidity and good vibration insulation. As in the human arm, the weakestcomponents of this kind of robot armare not the bones (i.e. the body tube) orthe muscles (i.e. the drive motor) but8handling tools within a three-dimensional space, and not just for robots.But most of the solutions available thus far have struggled to overcomethe negative interaction between the necessary drive on the rotating axisand the required arm stability. By eliminating the mass from movingparts, the forces of inertia in the arm are reduced. The arm jib is lighterin weight and can work more dynamically, while providing the same levelof stability.
rather the “tendons” which transfer thepower. The high-tension “tendons“ orcontrol cables are therefore made ofa highly wear resistant and tensile loadresistant fiber made from highly crystalline, UHMW-PE (ultra-high molecularweight polyethylene). With tensilestrength of 3000 to 4000 N/mm2, it onlybreaks under its intrinsic weight at alength of 400 km. This design allows aload / intrinsic weight ratio of 1:1 to beachieved, or even less if the structure isoptimized. As well as the traditional robotarm functions, the joint can be used fornew functions such as special fittingsfor cameras, sensors or tools where lightweight construction is key. In the future,it may even be used on prosthetics. It isthe separation of the tool, the movingparts, the control module and the actualdrive that make it ideal for mobile use.As the components that have been “eliminated“ from the moving parts representa sort of counterweight to the mass ofthe arm, the overall structure is very light.A magnetic angle position sensor is builtinto every joint to improve precision. Combined with the highly dynamic drives, thisproduces a precision-controlled robotmodule.Dynamic, powerful and compactCompact drive solutions are required inorder to operate the largest possiblenumber of cable controls within a confined space. Where high levels of dynamism, real power yield and precise, controllable use are required, electronicallycommuted servomotors like those fromFAULHABER are the best option. The smallcompact drives have a low moving massand an outstanding performance to volume ratio, making them ideal for dynamicuse. The excellent heat deflection allowsconsiderable overload when operated forshort periods rather than permanently,which is an additional advantage, especially when it comes to fast swivel movements. The operating voltage of 24 V DCis perfectly tailored to battery power,which is crucial for mobile applications.With a 32 mm diameter, a high permanent output with 80 % efficiency can beachieved in 4-quadrant mode. The 97 mNmtorque of the four-pole motors increasesthe diameter-compliant planetary gearheads to the values required to operatethe arm. Depending on the area of application for the swivel movement, the planetary gearheads allow transformation ratiosof 1:4 to 1600 or 6 to 20 Nm continuous torque at up to 96 % efficiency. Thestainless steel casing is as weatherproofas the plastic joints and cable controls.The fact that brushless drives have nowearing components apart from the rotorbearing guarantees a long service lifeover many tens of thousands of hours. Theprecision gearheads also boast a long nomaintenance service life. The motor canbe operated in a temperature range from– 40 to 100 C, the gearheads from –25to 90 C. This means they can both copewith environmental conditions from theArctic to the tropics and thus a wide rangeof industrial operating conditions. Modernservomotors are the tool of choice forvarious applications where movementis required in the construction process.High precision levels and a long service lifecombined with easy integration into thecontrol system mean they can be usedboth for mobile applications and in compact engineering.www.igus.comISSUEISSSSUEUE 2 2012010201010109
INDUSTRIAL MACHINERYSolar wafer productionin horizontal furnaceMICRODRIVES USED TO MOVE FURNACE LOGISTICSModern micro-electronics and photovoltaics “live“ on coated silicon chips.The most cost-effective way to produce them is to cut out individualtransistors, CPU chips and solar cells from large units known as siliconwafers. This means that the highly sterile silicon wafer has to be accurately and reproducibly coated with a range of different substances. Specialhorizontal furnaces are used for this process, as they allow the conditionsto be defined exactly for the relevant reaction. High-performance, extremely reliable modern microdrives are perfect for the furnace logistics,i.e. the loading and unloading of furnace pipes and the opening and closingof the furnace doors.10Virtually all modern electronic devicesare based on silicon chips incorporating arange of components, such as transistors.They need to be produced quickly and inlarge volumes in order to offer cost-effective pricing for individual chips. The chipsare therefore produced in large quantitieson what are known as “wafers”, which aresilicon sheets measuring between 100 and300 mm, and are then separated. Specificsurface treatment of the wafers is just aslikely to involve the atmospheric absorption of phosphorus and boron compoundsas chemical vapor deposition (CVD) atlow pressure. Tempress Systems B.V. fromVaassen in the Netherlands have deve-
loped a highly flexible range of horizontalfurnaces that offer chip manufacturers ahigh degree of flexibility. The furnaces areused for mass producing quality solar cellsbased on wafers. Robust microdrives developed by microdrive expert FAULHABERfrom Schönaich near Stuttgart are usedto load the individual furnace pipes. Theyalso automatically close the furnace doors,which is a crucial safety function as highlyreactive chemicals are used in the furnaces.Made-to-measure wafertreatmentProduction methods change in the electronics industry quicker than virtually anyother sector. So all the systems used needto have the capacity to adapt flexibly toa wide range of different productionrequirements. The horizontal furnaces putthese industry requirements into practicewith consummate perfection. The fourreaction furnace chambers are arrangedhorizontally above one another and areloaded with 156 mm x 156 mm wafers forthe production of solar cells. There arearound 400 to 500 wafers per pipe, so ittakes just a single process to coat up to1500 wafers per hour. In solar panel production, the surface area of a wafer canlater be used to generate an average of4 W of energy. If you consider that an average house roof has around 50 panelsproducing around 200 W each, the production output of the Tempress furnacerepresents solar electrical performance of30 to 35 MW per year. High throughputlevels allow cost-effective mass production of solar cells. Depending on the procedure, the furnaces either work undernormal pressure or in a vacuum, withtemperatures ranging between 380 and1380 C. Because the wafer sheets areexpensive, process reliability is crucial, andall the components need to satisfy exacting requirements. The Tempress DataManagement System allows a wide rangeof parameters to be configured, fromtemperature management through precise gas measurement to pressure control.There is a special loading system whichloads and unloads the individual furnacepipes. Microdrives are used as actuators.The main requirements of the drive are ahigh level of torque from a very compactdrive, plus precision positioning. It is alsoimperative that the drives are extremelyreliable. After all, errors can be veryexpensive because of the high cost levelsand the use of corrosive chemicals. Therobust design of the planetary gearheadswas also a decisive factor here. Otherbenefits of the actuators selected by thecompany included the compact design ofthe complete drive, with the matchingencoder, and its dynamism and intuitivecontrols.the precision of the drive shaft. There areeven more exacting requirements for thesafety-critical function of closing thefurnace door. A reliable locking systemmust be guaranteed in order to ensurethat gas cannot escape from the furnacepipes. This is why, as well as a motor withencoder and planetary gearheads, somemodels also have electromagnetic brakesinstalled. These guarantee that the doorsclose safely even in the event of a poweroutage. The brake unit also plugs into the32 mm motor, with the whole unit – including the motor – measuring just 72.5 mm.Modern microdrives offer all the functions of larger drives within a compactspace. Whether it‘s encoders, gearheadsor brakes, virtually all components arenow available in miniaturized form. Theirbest-in-class design guarantees high levelsof process reliability.www.tempress.nlfaulhaber.nlMicrodrives – robust and preciseVarious drive solutions from the FAULHABER range are deployed in the different furnaces. The loading systems, forexample, use a DC-Microdrive. The diameter-compliant planetary gearheadsreduce the speed and at the same timeincrease the drive torque. Depending onthe design (normal or heavy-loader), thedrives used have a diameter of 32 or38 mm and metal planetary gearheadswith transformation ratios of 14:1 or3.71:1. In both versions, there are plug-inencoders which allow precise positioningof the wafers in the system based on 256pulses per revolution of the motor shaft.The gear transformation also increasesISSUE 2 201201020100111
