In 1816, Werner von Siemens was born in a peasant family. Due to the limited financial conditions of the family, Siemens joined the army after graduating from middle school. He became very interested in the telegraph in the army, and invented and manufactured the compass telegraph (very popular at the time) The product).

In 1847, Siemens and engineer John George Halsk relied on the 6842 thaler silver coins invested by his cousin (1 thaler is equivalent to 3 marks) to establish the Siemens-Halsk Telegraph Manufacturing Company (abroad people like to use their own names as firm, as does British firm Martin Baker).
It mainly produces the compass telegraph invented by Siemens. This company is the predecessor of Siemens. In 1848, Siemens won the contract for the telegraph line from Frankfurt to Berlin, and it began to develop greatly.
As a physicist, Siemens' love for technology has directly affected the development of Siemens. In addition to managing the company, Siemens spends more time on research and invention.
In 1866, Siemens proposed the working principle of the generator, and an engineer from Siemens completed the first self-excited DC generator. In the same year, Siemens also invented the first DC motor.

These technologies developed by Siemens are often commercialized and put into the market immediately, or applied to new products. For example, electric locomotives (1879), elevators (1880), trams (1881), trolleybuses (1882), etc. were the first to be put on the market by Siemens with the invention of its founder.
Ironically, the electric car, which didn't start to develop until the end of the 20th century, was also invented by Siemens in 1898.

Siemens Combino trams are successfully running on the tracks of the eastern German city of Potsdam as part of an international transport fair, and the computer systems on these large, heavy vehicles have proven themselves to avoid risks to pedestrians and others.

Siemens SGT5-8000H super heavy gas turbine is the largest gas turbine in the world
Siemens—SGT5-8000H super heavy gas turbine is the largest gas turbine in the world, with a power 1.93 times that of the Nimitz aircraft carrier, and one can provide electricity for a large industrialized city. If the aero engine is the "flower of industry", then the super large gas turbine is the "crown jewel" of the industry.
picture
Heavy-duty gas turbines are the core of power equipment in the 21st century, and gas turbine technology is currently recognized as a key technology that marks the advanced level of a country's industrial foundation! Super-large gas turbines are generally recognized as the most difficult to manufacture: the price of a blade is equivalent to a BMW, and the slightest error is scrapped. Its power is equivalent to the sum of the engines of 13 Airbus A380 jetliners.
The power of 375MW is equal to 1.93 times of the total power (194MW) of the "Nimmitz" aircraft carrier! The power generation of a SGT5-8000H super large gas turbine is enough for an industrialized city!

Turbine blades of Siemens SGT5-8000H super heavy duty gas turbine
The turbine blades of Siemens SGT5-8000H ultra-heavy-duty gas turbines have to withstand a high temperature of over 1500°C, which exceeds the turbine inlet temperature of GE90 turbofan aeroengine and F404 jet engine.
picture
Due to the rotation of the turbine blades, huge centrifugal forces are at work. One end of each blade touches 10,000 times the gravitational force of the Earth, which is the maximum force per cubic centimeter equivalent of multiple blades of such a person weighing as an adult.
Through the special cooling used in the single crystal growth process of turbine blades, the grain boundaries in the alloy can break without any grains between. The turbine blade tip speed exceeds 1700 km/h, exceeding the speed of sound.

Siemens manufactures the world's largest slip ring motors. The motor is 19.08 meters high, 25.09 meters wide, and 2.7 meters thick. The total weight is about 640 tons, and the weight of a single piece is 100 tons. The entire stator part of the motor is divided into 4 pieces, which are hoisted and assembled separately. It is currently the largest slip ring motor in the world.

NASA assembled and built Curiosity based on precise simulation designs provided by Siemens PLM. "Curiosity", the most complex space probe of mankind, can be described as a process of fusion from virtual to reality.
Siemens provided NASA with PLM intelligent software, covering the entire process of R&D and testing of Curiosity. For example, the "air landing machine", landing on Mars, etc. are all simulated by the software for thousands of times, which greatly increases the possibility of its success.

Siemens' PLM series software optimizes the CNC machine tools of Mori Seiki (Japan), and applies computers to the process or system of the manufacturing process. The feature of CNC is to control the machine tool by the program instructions encoded on the perforated paper tape. The automatic tool change and automatic conversion of working positions in the library can continuously complete multiple processes such as sharpening, drilling, stirring, and tapping.
This halved the design-to-manufacture time for Mori Seiki's CNC machine tools and increased the ability to release more new products.

Siemens in China
Siemens has always enjoyed a global reputation as an international company. After the company was established 25 years ago (1872), Siemens started business with China. Siemens' first order in China was to provide pointer telegraphs to China, which marked the beginning of China's modern telecommunications industry.
In early 1879, Siemens received an order for "lighting equipment" from the Chinese government. Siemens provided a 10-horsepower steam generator for the lighting of Shanghai Port, which greatly improved the working efficiency of the port. Siemens applied the revolutionary generator to the land of China for the first time, thus entering the annals of Chinese history.
picture
Siemens' business in China, especially in the power field, developed rapidly in the early 20th century. In 1910, China's first large-scale hydropower station, the Shilongba Hydropower Station, was built in Yunnan Province, and the generators were manufactured by Siemens AG of Germany. So far, Siemens motors are still operating normally, and the hydropower station is also known as a wonder in the Spring City of Kunming.
