It enables contactless, synchronised transmission of torques between two shafts without mechanical contact or friction. The magnets are arranged in such a way that they generate a common magnetic field that causes the shafts to rotate at exactly the same rate. This contactless transmission makes them an extremely reliable solution, especially in demanding industrial applications.<\/h6>\n<p>&nbsp;<\/p>\n<h6>Metau magnetic couplings are available with neodymium magnets (Ne), with which a torque range of 9.4 to 580 Nm is available, and alternatively with samarium cobalt (SmCo) for a range of 6 to 380 Nm. The magnetic couplings with neodymium magnets can be used up to a temperature of 120\u00b0C and those with samarium cobalt magnets up to a temperature of 300\u00b0C.<\/h6>\n<p>&nbsp;<\/p>\n<h6>Depending on the required pressure resistance, chemical resistance and the need for as little or no eddy current loss as possible, various materials are available for the containment shroud. You can choose between stainless steel, titanium and technopolymer (PEEK). Metau magnetic couplings can also be supplied in accordance with ATEX.<\/h6>\n[\/vc_column_text][\/toggle][toggle color=&#8221;Accent-Color&#8221; heading_tag=&#8221;h2&#8243; heading_tag_functionality=&#8221;default&#8221; title=&#8221;How magnetic couplings work&#8221;][vc_column_text]\n<h6>The permanent magnetic synchronising coupling is an innovative technology based on the principle of contactless magnetic force transmission. It enables a precise and maintenance-free connection between two shafts without the need for mechanical contact or friction.<\/h6>\n<p>&nbsp;<\/p>\n<h6><strong>Structure and components:<\/strong><br \/>\nThere are two main components inside the clutch: the input side (primary side) and the output side (secondary side). Both sides are equipped with permanent magnets that are strategically placed to create a common magnetic field. The magnets are positioned so that they attract each other and create a stable connection when the shafts rotate.<\/h6>\n<p>&nbsp;<\/p>\n<h6><strong>Magnetic field and synchronisation:<\/strong><br \/>\nThe permanent magnets on both sides are aligned to create a synchronous magnetic field. This means that the magnetic poles are arranged in such a way that they attract each other when the shafts rotate at the same rate. This magnetic field acts like an invisible bridge that transmits the rotary motion from the input shaft to the output shaft.<\/h6>\n<p>&nbsp;<\/p>\n<h6><strong>Torque transmission without contact:<\/strong><br \/>\nWhen the drive shaft is set in motion, the permanent magnets generate a magnetic field that also rotates the output shaft. As there is no mechanical contact, there is no friction or wearing parts. Power is transmitted exclusively by the magnetic field, which makes the magnetic coupling extremely low-maintenance.<\/h6>\n<p>&nbsp;<\/p>\n<h6><strong>Automatic synchronisation:<\/strong><br \/>\nA decisive advantage is the magnetic coupling&#8217;s ability to synchronise the shafts precisely. The magnetic field ensures that the speeds of both shafts always match. If the output side is decelerated or accelerated by external influences, the magnetic field automatically adjusts to ensure precise synchronisation.<\/h6>\n<p>&nbsp;<\/p>\n<h6><strong>Decoupling in the event of overload:<\/strong><br \/>\nIn the event of an overload or blockage, the magnetic coupling can decouple automatically. This means that the magnetic fields separate to prevent damage to the system. As soon as the load returns to the normal range, the magnetic coupling re-establishes the connection &#8211; all without contact or mechanical intervention.<\/h6>\n[\/vc_column_text][\/toggle][toggle color=&#8221;Accent-Color&#8221; heading_tag=&#8221;h2&#8243; heading_tag_functionality=&#8221;default&#8221; title=&#8221;Advantages of magnetic couplings&#8221;][vc_column_text]\n<h6>Magnetic couplings offer a number of advantages that make them a favoured solution in industrial drive technology:<\/h6>\n<p>&nbsp;<\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li>\n<h6><strong>Contactless power transmission:<\/strong> As there are no mechanical contacts, magnetic couplings are wear-free and require hardly any maintenance.
