If you’re curious about how to use a plate demagnetiser, read on! Demagnetizers are designed to remove residual magnetism from metals. They work by using deep frequencies and multiples of mains voltage instead of electricity to remove magnetism from metals. However, the demagnetizers are not without their drawbacks, and you’ll need to know how to use one properly.
Maurer Magnetic patent protects demagnetisers from earth’s magnetic field
One patent from Maurer Magnetic AG, the German magnetism company, protects plate demagnetisers from the earth’s magnetic field. This new technology uses high intensity, pulsed magnetic fields to eliminate residual magnetism in large-surface components. The patent also covers demagnetisation of materials in bulk, which are often large and stretched. A demagnetiser’s effectiveness is determined by how accurately it is able to decrease the magnetic field.
The Maurer Degaussing(r) method operates by generating alternating pulses of high field strength. These pulses are used to demagnetise components without disassembling them. This saves time and prevents lost settings when disassembling them. Pulse demagnetisers can demagnetise large assemblies in just seconds.
The Maurer Magnetic patent is one of the oldest in the world. It was first filed on 2015-06-24 by Albert MAURER, JR., together with Marek Rohner, Boris Ziegenhagen and others. The patent is a vital piece of technology that protects plate demagnetisers from the earth’s magnetic field.
A plate demagnetiser works by using a parallel resonant circuit that consists of a demagnetising coil and a parallel capacitor. When a supply of AC voltage is switched off, the current amplitude in the circuit automatically decays. In this way, a magnetic alternating field with decreasing amplitude can be generated without control.
Maurer Magnetic technology uses multiple of the mains voltage
The plate demagnetisers used by Maurer Magnetic technology use a plate demagnetiser with a higher power of magnetic field than those used in traditional techniques. The stronger magnetic fields ensure complete demagnetisation inside the material. The plates of the demagnetizers are made of a high-grade iron-based material. They are therefore ideal for removing residual magnetism from bulk goods, which often contains large metals.
Maurer Magnetic technology uses a power module to enhance the demagnetizing process. A plate demagnetizer powered by this technology operates at a multiple of the mains voltage. It can demagnetize large work pieces as well as many parts at the same time. The control interface allows simple integration into automated processes. The industrial duty demagnetizer MM DN + CT-U uses a multiple of the mains voltage to operate.
The global market for plate demagnetizers covers the North America, South America, Asia-Pacific countries, Middle East, China, and India. This report will provide a comprehensive analysis of the market and its future prospects. The report is divided into various sections such as Type, Application, and Region. While the global Plate Demagnetizer market is estimated at over $1.4 billion, it will grow at a significant rate during the next few years.
In Maurer Magnetic technology, multiple of the mains voltage is used to operate a plate demagnetizer. The frequency of the excitation should be chosen in such a way that the product of f*L0?22 Hz*H is produced. Once this frequency is reached, the plate demagnetizer operates. The resonant circuit is a series of coils connected in parallel.
Maurer Magnetic technology uses deep frequencies
Maurer Magnetic AG develops demagnetizers for hard steel parts and bulk materials. These machines have powerful magnetic fields generated by rare earth magnets. A stray field is generated over the top panel of the machine, which is larger than the plate demagnetizer’s field. This stray field is powerful enough to de-magnetize large single parts and bulk materials. Depending on the type of demagnetiser being used, these devices can de-magnetize hard steel tools to 10 mm.
The plate demagnetizer is controlled manually or automatically. The alternating field reaches its maximum at the centre of the plate. The pulse button activates the field decline function. The part is placed in the middle of the top panel and the device demagnetises it automatically. The demagnetizer can also be used for a single part. The device features a field decline function for demagnetising parts automatically.
The maximum field strength is one of the most important parameters in the demagnetisation process. The maximum field strength should last for the entire duration of a complete sine wave. The maximum alternating current is limited by ohmic and inductive resistances. The maximum field strength can be increased by adjusting the maximum demagnetizing frequency, thereby compensating for the apparent power.
Demagnetisation of hard ferrite magnets is a relatively simple process. In most cases, the demagnetisation process involves pulling a component through a tunnel or over a demagnetiser to make it magnetically neutral. By reducing the amount of alternating magnetic field, the component is still subjected to sufficient vibrations to become polarised.
Maurer Magnetic technology uses rare earth magnets instead of electricity
In contrast to traditional electrical demagnetisation, Maurer Magnetic uses rare earth magnets instead of electricity. The resulting demagnetisation process ensures perfect demagnetisation, high productivity and reduced risk of failure. Maurer Magnetic technology uses a customised frequency setting in the factory for each component, to optimise demagnetisation cycle times and yields. Rare earth magnets can operate with fields of up to 5 Tesla and are therefore incomparable to electricity.
To achieve similar hard magnetic properties, rare earth magnets should have the same composition. For example, Alnico magnets are made of thirty-five percent aluminum, thirty-five percent nickel, and 15 percent cobalt. This alloy was developed in the 1930s and gained popularity in the 1940s. However, Alnico magnets are easily demagnetized and require proper storage.
According to a study by Harris, I.C., Evans, J.M., and Nyholm, P.S., the Maurer Magnetic technology uses rare earth magnets instead of electricity to demagnetize plates. They describe the process in detail and demonstrate its advantages. The researchers say that the technology has the potential to revolutionise demagnetisation of plates.
Another promising technology involves nanowire-ferrite composites. These nanowire-ferrite composites may fill the gap between rare-earth magnets and ferrites. Nonetheless, the main bottleneck to industrial implementation is the high cost and low yield of these materials. However, there are several strategies underway to overcome these problems. If successful, nanowire-ferrite composites will become the next generation of rare-earth magnets.
