An actuator is a component of a machine that produces force , torque , or displacement , when an electrical , pneumatic or hydraulic input is supplied to it in a system (called an actuating system ). The effect is usually produced in a controlled way. An actuator translates such an input signal into the required form of mechanical energy . It is a type of transducer . In simple terms, it is a "mover".
100-485: Sønderborg ( Danish pronunciation: [ˈsønɐˌpɒˀ] ; German : Sonderburg [ˈzɔndɐbʊʁk] ) is a Danish town in the Region of Southern Denmark . It is the main town and the administrative seat of Sønderborg Municipality (Kommune). The town has a population of 28,277 (1 January 2024), in a municipality of 74,233. In recent times, Sønderborg is a center for trade, tourism, industry, and education in
200-460: A de facto official language of Namibia after the end of German colonial rule alongside English and Afrikaans , and had de jure co-official status from 1984 until its independence from South Africa in 1990. However, the Namibian government perceived Afrikaans and German as symbols of apartheid and colonialism, and decided English would be the sole official language upon independence, stating that it
300-489: A linear motor , which can be thought as a rotary electric motor which has been cut and unrolled. Thus, instead of producing a rotational movement, it produces a linear force along their length. Because it generally has lower friction losses than the alternatives, a linear electric actuator can last over a hundred million cycles. Linear motors are divided in 3 basic categories: flat linear motor (classic), U-Channel linear motors and Tubular linear motors. Linear motor technology
400-427: A mechanism that is directly driven by the motions or forces of other parts of the system. An example is the camshafts that drive the intake and exhaust valves in internal combustion engines , driven by the engine itself. Another example is the mechanism that strikes the hours in a traditional grandfather clock or cuckoo clock . A hydraulic actuator typically uses the pressure of a liquid (usually oil) to cause
500-402: A second language , and 75–100 million as a foreign language . This would imply the existence of approximately 175–220 million German speakers worldwide. German sociolinguist Ulrich Ammon estimated a number of 289 million German foreign language speakers without clarifying the criteria by which he classified a speaker. As of 2012 , about 90 million people, or 16% of

Cameroon was also a colony of the German Empire from the same period (1884 to 1916). However, German was replaced by French and English, the languages of the two successor colonial powers, after its loss in World War I . Nevertheless, since the 21st century, German has become
700-432: A (non-electronic) thermostat contains a strip with two layers of different metals, that will bend when heated. Thermal actuators may also exploit the properties of shape-memory alloys . Some actuators are driven by externally applied magnetic fields . They typically contain parts made of ferromagnetic materials that are strongly attracted to each other when they are magnetized by the external field. An example are
800-414: A ball or a lead screw or planetary roller screw). The main advantages of electromechanical actuators are their relatively good level of accuracy with respect to pneumatics, their possible long lifecycle and the little maintenance effort required (might require grease). It is possible to reach relatively high force, on the order of 100 kN. The main limitation of these actuators are the reachable speed,

Sønderborg is an economic hub in the region of Southern Denmark , with industries within electronics , manufacturing , food processing , Information Technology and telecommunications among others, with several companies headquartered in and around
1000-556: A greater need for regularity in written conventions. While the major changes of the MHG period were socio-cultural, High German was still undergoing significant linguistic changes in syntax, phonetics, and morphology as well (e.g. diphthongization of certain vowel sounds: hus (OHG & MHG "house") → haus (regionally in later MHG)→ Haus (NHG), and weakening of unstressed short vowels to schwa [ə]: taga (OHG "days")→ tage (MHG)). A great wealth of texts survives from
1100-430: A linear motion, but is not a linear motor ). Another broad classification of actuators separates them into two types: incremental-drive actuators and continuous-drive actuators. Stepper motors are one type of incremental-drive actuators. Examples of continuous-drive actuators include DC torque motors , induction motors , hydraulic and pneumatic motors , and piston-cylinder drives (rams). An actuator can be just

1300-453: A native tongue today, mostly descendants of German colonial settlers . The period of German colonialism in Namibia also led to the evolution of a Standard German-based pidgin language called " Namibian Black German ", which became a second language for parts of the indigenous population. Although it is nearly extinct today, some older Namibians still have some knowledge of it. German remained
1400-574: A new pathway for fabricating low-cost and fast response SMP actuators. The process of receiving external stimuli like heat, moisture, electrical input, light or magnetic field by SMP is referred to as shape memory effect (SME). SMP exhibits some rewarding features such a low density, high strain recovery, biocompatibility, and biodegradability . Photopolymers or light activated polymers (LAP) are another type of SMP that are activated by light stimuli. The LAP actuators can be controlled remotely with instant response and, without any physical contact, only with
1500-432: A piston to slide inside a hollow cylindrical tube linear, rotatory or oscillatory motion. In a single acting actuator the fluid pressure is applied to just one side of the piston, so that it applies useful force in only one direction. The opposite motion may be effected by a spring , by gravity, or by other forces present in the system. In a double acting actuator, the return stroke is driven by fluid pressure applied to
1600-679: A popular foreign language among pupils and students, with 300,000 people learning or speaking German in Cameroon in 2010 and over 230,000 in 2020. Today Cameroon is one of the African countries outside Namibia with the highest number of people learning German. In the United States, German is the fifth most spoken language in terms of native and second language speakers after English, Spanish , French , and Chinese (with figures for Cantonese and Mandarin combined), with over 1 million total speakers. In

At this point monasteries, where most written works were produced, were dominated by Latin, and German saw only occasional use in official and ecclesiastical writing. While there is no complete agreement over the dates of the Middle High German (MHG) period, it
1800-414: A single step by rapid prototyping methods, such as 3D printing , are utilized to narrow the gap between the design and implementation of soft actuators, making the process faster, less expensive, and simpler. They also enable incorporation of all actuator components into a single structure eliminating the need to use external joints , adhesives , and fasteners . Shape memory polymer (SMP) actuators are
1900-463: A subdivision of transducers. They are devices which transform an input signal (mainly an electrical signal ) into some form of motion. Motors are mostly used when circular motions are needed, but can also be used for linear applications by transforming circular to linear motion with a lead screw or similar mechanism. On the other hand, some actuators are intrinsically linear, such as piezoelectric actuators. Conversion between circular and linear motion

German is the official language of the following countries: German is a co-official language of the following countries: Although expulsions and (forced) assimilation after the two World wars greatly diminished them, minority communities of mostly bilingual German native speakers exist in areas both adjacent to and detached from the Sprachraum. Within Europe, German
2700-582: Is commonly made via a few simple types of mechanism including: In virtual instrumentation , actuators and sensors are the hardware complements of virtual instruments. Performance metrics for actuators include speed, acceleration, and force (alternatively, angular speed, angular acceleration, and torque), as well as energy efficiency and considerations such as mass, volume, operating conditions, and durability, among others. When considering force in actuators for applications, two main metrics should be considered. These two are static and dynamic loads. Static load

Electric actuators can be classified in the following groups: An electromechanical actuator (EMA) uses mechanical means to convert the rotational force of an ordinary (rotary) electric motor into a linear movement. The mechanism may be a toothed belt or a screw (either
3000-520: Is generally seen as ending when the 1346–53 Black Death decimated Europe's population. Modern High German begins with the Early New High German (ENHG) period, which Wilhelm Scherer dates 1350–1650, terminating with the end of the Thirty Years' War . This period saw the further displacement of Latin by German as the primary language of courtly proceedings and, increasingly, of literature in

Approximate distribution of native German speakers (assuming a rounded total of 95 million) worldwide: As a result of the German diaspora , as well as the popularity of German taught as a foreign language , the geographical distribution of German speakers (or "Germanophones") spans all inhabited continents. However, an exact, global number of native German speakers
4400-447: Is used to actuate equipment such as multi-turn valves, or electric-powered construction and excavation equipment. When used to control the flow of fluid through a valve, a brake is typically installed above the motor to prevent the fluid pressure from forcing open the valve. If no brake is installed, the actuator gets activated to reclose the valve, which is slowly forced open again. This sets up an oscillation (open, close, open ...) and
4500-458: Is what most of the actuators are used for. For most actuators they are mechanically durable yet do not have an ability to adapt compared to soft actuators. The soft actuators apply to mainly safety and healthcare for humans which is why they are able to adapt to environments by disassembling their parts. This is why the driven energy behind soft actuators deal with flexible materials like certain polymers and liquids that are harmless The majority of
4600-673: The Ostsiedlung ). With the increasing wealth and geographic spread of the Germanic groups came greater use of German in the courts of nobles as the standard language of official proceedings and literature. A clear example of this is the mittelhochdeutsche Dichtersprache employed in the Hohenstaufen court in Swabia as a standardized supra-dialectal written language. While these efforts were still regionally bound, German began to be used in place of Latin for certain official purposes, leading to

6400-675: The Germanic dialects that were affected by the High German consonant shift (south of Benrath) from those that were not (north of Uerdingen). The various regional dialects spoken south of these lines are grouped as High German dialects, while those spoken to the north comprise the Low German and Low Franconian dialects. As members of the West Germanic language family, High German, Low German, and Low Franconian have been proposed to be further distinguished historically as Irminonic , Ingvaeonic , and Istvaeonic , respectively. This classification indicates their historical descent from dialects spoken by
6500-646: The Irminones (also known as the Elbe group), Ingvaeones (or North Sea Germanic group), and Istvaeones (or Weser–Rhine group). Standard German is based on a combination of Thuringian - Upper Saxon and Upper Franconian dialects, which are Central German and Upper German dialects belonging to the High German dialect group. German is therefore closely related to the other languages based on High German dialects, such as Luxembourgish (based on Central Franconian dialects ) and Yiddish . Also closely related to Standard German are

However, these methods require manual fabrication of devices, post processing/assembly, and lengthy iterations until maturity in the fabrication is achieved. To avoid the tedious and time-consuming aspects of the current fabrication processes, researchers are exploring an appropriate manufacturing approach for effective fabrication of soft actuators. Therefore, special soft systems that can be fabricated in

Another approach is an electrohydraulic actuator , where the electric motor remains the prime mover but provides torque to operate a hydraulic accumulator that is then used to transmit actuation force in much the same way that diesel engine/hydraulics are typically used in heavy equipment . Electrical energy
7800-474: The influence of Luther's Bible as an unofficial written standard, a widely accepted standard for written German did not appear until the middle of the eighteenth century. German was the language of commerce and government in the Habsburg Empire , which encompassed a large area of Central and Eastern Europe . Until the mid-nineteenth century, it was essentially the language of townspeople throughout most of
7900-543: The island of Funen , with roads connecting the town to Odense and further to Zealand and Copenhagen . The formerly ruling family of Schleswig-Holstein-Sonderburg married into Kings and Queens Sønderborg is home to the South Jutland Symphony Orchestra Sønderjyllands Symfoniorkester . Sønderborg Castle is today a museum about the history of Southern Denmark. The science park Universe (earlier known as Danfoss univers)
8000-455: The largest concentrations of German speakers are in the states of Rio Grande do Sul (where Riograndenser Hunsrückisch developed), Santa Catarina , and Espírito Santo . Actuators An actuator requires a control device (which provides control signal ) and a source of energy . The control signal is relatively low in energy and may be voltage , electric current , pneumatic , or hydraulic fluid pressure , or even human power . In
8100-404: The most similar to our muscles, providing a response to a range of stimuli such as light, electrical, magnetic, heat, pH, and moisture changes. They have some deficiencies including fatigue and high response time that have been improved through the introduction of smart materials and combination of different materials by means of advanced fabrication technology. The advent of 3D printers has made
8200-402: The mother in the home and the plain man would say, Wesz das Herz voll ist, des gehet der Mund über . Luther's translation of the Bible into High German was also decisive for the German language and its evolution from Early New High German to modern Standard German. The publication of Luther's Bible was a decisive moment in the spread of literacy in early modern Germany , and promoted
8300-405: The motor and actuator will eventually become damaged. Electric rotary actuators use a rotary motor to turn the target part over a certain angle. Rotary actuators can have up to a rotation of 360 degrees. This allows it to differ from a linear motor as the linear is bound to a set distance compared to the rotary motor. Rotary motors have the ability to be set at any given degree in a field making
8400-630: The ninth century, chief among them being the Muspilli , Merseburg charms , and Hildebrandslied , and other religious texts (the Georgslied , Ludwigslied , Evangelienbuch , and translated hymns and prayers). The Muspilli is a Christian poem written in a Bavarian dialect offering an account of the soul after the Last Judgment , and the Merseburg charms are transcriptions of spells and charms from
8500-427: The opposite side of the piston. Since liquids are nearly impossible to compress, a hydraulic actuator can exert a large force. The drawback of this approach is its limited acceleration. They respond quickly to input changes, have little inertia, can operate continuously over a relatively large working range, and can hold their position without any significant energy input. A hydraulic actuator can be used to displace
8600-462: The pronunciation of the ending -ig as [ɪk] instead of [ɪç]. In Northern Germany, High German was a foreign language to most inhabitants, whose native dialects were subsets of Low German. It was usually encountered only in writing or formal speech; in fact, most of High German was a written language, not identical to any spoken dialect, throughout the German-speaking area until well into the 19th century. However, wider standardization of pronunciation
8700-408: The rack of a rack and pinion mechanism, causing the pinion to turn. This arrangement is used, for example, to operate valves in pipelines and other industrial fluid transport installations. A pneumatic actuator is similar to a hydraulic one but uses a gas (usually air) instead of a liquid. Compared to hydraulic actuators, pneumatic ones are less complicated because they do not need pipes for
8800-525: The region of Southern Denmark . The town is the headquarters for several industrial companies. Sønderborg joined the UNESCO Global Network of Learning Cities in 2016. The town of Sønderborg is home to Sønderborg Castle ( Sønderborg Slot ), the Royal Danish Army 's Sergeant School (until 2013) and Sandbjerg Estate ( Sandbjerg Gods ). Sønderborg castle is in the centre of the town, and houses
8900-421: The return and recycling of the working fluid. On the other hand, they still need external infrastructure such as compressors, reservoirs, filters, and air treatment subsystems, which often makes them less convenient that electrical and electromechanical actuators. In the first steam engines and in all steam locomotives , steam pressure is used to drive pneumatic actuators to produce a reciprocating motion, which
9000-405: The rotary actuators are just about endless but, will more than likely be found dealing with mostly hydraulic pressured devices and industries. Rotary actuators are even used in the robotics field when seeing robotic arms in industry lines. Anything you see that deals with motion control systems to perform a task in technology is a good chance to be a rotary actuator. A linear electric actuator uses
9100-541: The states of North Dakota and South Dakota , German is the most common language spoken at home after English. As a legacy of significant German immigration to the country , German geographical names can be found throughout the Midwest region , such as New Ulm and Bismarck (North Dakota's state capital), plus many other regions. A number of German varieties have developed in the country and are still spoken today, such as Pennsylvania Dutch and Texas German . In Brazil,
9200-496: The third most commonly learned second language in the United States in K-12 education. The language has been influential in the fields of philosophy, theology, science, and technology. It is the second most commonly used language in science and the third most widely used language on websites . The German-speaking countries are ranked fifth in terms of annual publication of new books, with one-tenth of all books (including e-books) in
9300-461: The town. The high-tech industry includes the manufacturing and development of electronics, machines, industrial equipment, and software. Companies of major importance in the high-tech sector headquartered in the region include Danfoss who employs around 1000 people in Sønderborg, and 40,000 people globally. Linak, headquartered in Nordborg 25 km from Sønderborg, produces linear actuators for
9400-852: The variation of light frequency or intensity. A need for soft, lightweight and biocompatible soft actuators in soft robotics has influenced researchers for devising pneumatic soft actuators because of their intrinsic compliance nature and ability to produce muscle tension. Polymers such as dielectric elastomers (DE), ionic polymer–metal composites (IPMC), ionic electroactive polymers, polyelectrolyte gels, and gel-metal composites are common materials to form 3D layered structures that can be tailored to work as soft actuators. EAP actuators are categorized as 3D printed soft actuators that respond to electrical excitation as deformation in their shape. In engineering , actuators are frequently used as mechanisms to introduce motion , or to clamp an object so as to prevent motion. In electronic engineering, actuators are
9500-468: The watchmaking, semiconductor and pharmaceutical industries (as high as 60% of the applications. The growing interest for this technology, can be explained by the following characteristics: The main disadvantages of linear motors are: An actuator may be driven by heat through the expansion that most solid material exhibit when the temperature increases. This principle is commonly used, for example, to operate electric switches in thermostats . Typically,
9600-543: The world being published in German. German is most closely related to other West Germanic languages, namely Afrikaans , Dutch , English , the Frisian languages , and Scots . It also contains close similarities in vocabulary to some languages in the North Germanic group , such as Danish , Norwegian , and Swedish . Modern German gradually developed from Old High German , which in turn developed from Proto-Germanic during
9700-579: The written form of German. One of the central events in the development of ENHG was the publication of Luther's translation of the Bible into High German (the New Testament was published in 1522; the Old Testament was published in parts and completed in 1534). Luther based his translation primarily on the Meißner Deutsch of Saxony , spending much time among the population of Saxony researching
9800-429: Was a "neutral" language as there were virtually no English native speakers in Namibia at that time. German, Afrikaans, and several indigenous languages thus became "national languages" by law, identifying them as elements of the cultural heritage of the nation and ensuring that the state acknowledged and supported their presence in the country. Today, Namibia is considered to be the only German-speaking country outside of
9900-530: Was an artificial standard that did not correspond to any traditional spoken dialect. Rather, it was based on the pronunciation of German in Northern Germany, although it was subsequently regarded often as a general prescriptive norm, despite differing pronunciation traditions especially in the Upper-German-speaking regions that still characterise the dialect of the area today – especially
10000-485: Was established on the basis of public speaking in theatres and the media during the 20th century and documented in pronouncing dictionaries. Official revisions of some of the rules from 1901 were not issued until the controversial German orthography reform of 1996 was made the official standard by governments of all German-speaking countries. Media and written works are now almost all produced in Standard German which
