Siemens expands motor portfolio for machine tools


EMO 2015, Hall 3, Booth E06/F03

  • Dynamic motor for large machine tools
  • Geared motor for auxiliary units such as pallet changers and chip conveyors
  • High-torque spindle motors for heavy machinery
  • Flexible segment motor for rotary tables and spindles

Siemens is unveiling numerous electric motors for use in machine tools. Covering a wide range of applications and offering outstanding torque, the new developments include the Simotics S-1FT7 compact synchronous servomotor with shaft height 132 as well as the Simotics S-1FG1 servo geared motor, which is available in a variety of models. Other innovations being presented are the powerful Simotics M-1FE2 built-in motor in size 180 and high-torque segment motors for use in large rotary tables and spindles.

Despite its compact size, the naturally cooled Simotics S1FT7 servomotor with shaft height 132 features a higher torque and consumes less power than previous models. The servomotor provides 90 to 170 newton meters (Nm) of torque depending on its length, making it especially suitable for large machine tools. With its new Simotics S-1FG1 servo geared motors, Siemens is expanding its motor portfolio for machine tools. The four types of gears and different gear ratios enable users to select the ideal configuration to meet their needs. Due to its superior energy efficiency and flexible torque ratio, the servo geared motor is especially suitable for use with auxiliary units such as pallet changers, chip conveyors, and feeder units.

The Simotics M-1FE2 built-in motor in size 180 has been designed for machining larger workpieces. The use of permanent magnets allows the spindle motor to achieve a particularly high torque density. With its high performance and internal diameter of 200 millimeters, the Simotics M-1FE2 is also suitable for use in large turning and milling centers as well as for sophisticated machining processes. Siemens also offers Simotics T-1FW68 high-performance segment motors. With a high torque of up to 1 million Nm, these direct drives can handle large to very large diameters. The segment motors allow for flexible configuration and can also be operated with a smaller number of stator segments.

Im Focus: Space observation with radar to secure Germany's space infrastructure

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.

The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...

Im Focus: Researchers Discover New Anti-Cancer Protein

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.

The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...

Im Focus: Researchers at Fraunhofer monitor re-entry of Chinese space station Tiangong-1

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.

Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

Im Focus: Alliance „OLED Licht Forum“ – Key partner for OLED lighting solutions

Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP, provider of research and development services for OLED lighting solutions, announces the founding of the “OLED Licht Forum” and presents latest OLED design and lighting solutions during light+building, from March 18th – 23rd, 2018 in Frankfurt a.M./Germany, at booth no. F91 in Hall 4.0.

They are united in their passion for OLED (organic light emitting diodes) lighting with all of its unique facets and application possibilities. Thus experts in...

Im Focus: Mars' oceans formed early, possibly aided by massive volcanic eruptions

Oceans formed before Tharsis and evolved together, shaping climate history of Mars

A new scenario seeking to explain how Mars' putative oceans came and went over the last 4 billion years implies that the oceans formed several hundred million...
