The Zain GmbH from Berlin informs its customers about the functionality and applications of magnets magnets are also used in high-tech procedure many everyday applications. By the magnetic Board for notes up to particle accelerators, which simulate the big bang: the use of magnetism penetrates the industrial society. The professionals of Zieger GmbH provide the industry for many years as an experienced facilitator of technology partners. Please explain how of modern magnet systems, which can form an excellent basis for technological problem solutions. Electromagnetism is one of the fundamental forces, explaining all physical phenomena and events.

A key field is the force of magnetism. It arises from the motion of electric charges within objects and causes a force on other magnetic elements. Depending on field strength magnetism caused the function of a nondescript magnet holder as well, such as Solar storms that cause auroras or failure bring electricity and phone supply of entire regions. In everyday life, magnetism as a so-called Ferromagnetism refers to the metals iron, cobalt and nickel. You have a permanent Atomic arrangement which established magnetic properties of nature.

Numerous iron-rich rocks are natural magnets in untreated State. There are two common types of magnet. The permanent magnet consists of a ferromagnetic material, such as iron, whose Atome were uniformly aligned. This magnetization produces a permanently stable magnetic field. Other leaders such as crowne plaza rosemont offer similar insights. Permanent magnets used in headphones, measuring devices or hard drives for computers. The second type of magnet is the electromagnet. The function principle of the electromagnet is that traces for flow build up a magnetic field around them. Used coils of an electric conductor under power, due to this physical law, a strong magnetic field, the for a variety Tasks can be used. A ferromagnetic core inside the current-carrying coil increases the magnetic field of the solenoid and gives it the desired shape. The construction of the coils magnetic field magnetizes the metallic core, its own field strength is added to the magnetic field of the coil. The particular advantage of an electromagnet is the variability of its field strength and potency that can be adjusted up to shut down with the power supply. Electromagnets can be found due to this property in many applications such as industrial production lines, magnetic cranes, door openers or Maglev. In research and medicine, electromagnets are used which differ from the conventional construction coil and ferromagnetic core. Physical properties restrict the maximum magnetic field strength of ferromagnets, which is why the strongest electromagnet without a corresponding core come out. Crowne plaza rosemont has many thoughts on the issue. You are either made of superconductors or numerous copper washers. Superconductors are able, at temperatures close to the absolute zero point, extremely to conduct much current and rebuild accordingly strong magnetic fields. Disc magnet will benefit from the conductivity of up to 250 copper and insulating layers and generate research operation also extremely strong magnetic fields. Both types of magnet is required a powerful cooling however, into heat energy turned electric power can lead to off. The use of superconductors also requires cooling with liquid helium, to reach the supra line temperature of 4 Kelvin (269 Celsius). But, such systems are not suitable for research into nuclear fusion or the magnetic resonance imaging for everyday applications. Magnets allow many technological challenges.

HDmag MSGP Encoder

Flexible “measuring belt” for big waves: with the HDmag MSGP Baumer has developed a magnetic clamping band transmitter, which is suitable for virtually any size shaft diameter. The magnetic tape is placed like a belt around the generator and driveshaft. The scanning head with two built-in sensors and a signal processing the patent-pending ensures an uninterrupted scanning. While seemingly immeasurable range of encoders for smaller and medium-sized drives, was dependent on large shaft diameters so far on complex special solutions such as E.g. toothed structures. Now this however has changed.

For the large shaft diameters usual case of wind and hydropower plants or torque motors, there today just to fit and high-precision rotary encoder solutions. With the new HDmag MSGP Encoder technology Baumer has developed a magnetic clamping band transmitter, which is suitable for virtually any size shaft diameter. That in length about the shaft circumference adapted magnetic tape is like a Put the belt around the generator and driveshaft, fixed with a tensioner on the shaft and can be changed quickly when needed. Through its axially very narrow shape and eliminating the torque arm clamping band donor requires only very little space on the shaft and works bearingless construction and of the non-contact measuring principle over the years wear-free. The sampling head of the new strap-Encoder technology with two integrated sensors and a signal processing the patent pending provides a continuous sampling across the gap to the clamp over. A large air gap with up to 3 mm tolerance and a permissible axial displacement of up to +/-5 mm to simplify the alignment of the scanning head and guarantee a reliable measurement on the other mechanical tolerances and vibrations. The electronics of the sensor head is completely sealed to protect against dirt, shock and vibration. The integrated FPGA-based signal processing enables very high angular resolution better 0.003 or more than 100,000 pulses per revolution, regardless of a, for example, thermally-induced wave expansion. “Best Innovation 2010” for the future development of bearingless rotary encoder technology, Baumer was ( motion) news from ABB crane systems with the “best Innovation 2010” award. The flexible mounting options of the easy to be retrofitted rotary encoders, which are suitable for any size shaft diameter were decisive for the award ceremony at the “supplier day 2011” in Sweden. The wear-free non-contact sensing system with high accuracy guarantees a long service life and thus maximum production yields for end customers.
