This innovative magnetic material is critical to boosting performance in the aerospace, automotive and motorsport industries, providing superior power density without adding weight.<\/p>\n\n\n\n<p>Arnold produces high performance permanent magnet motor components and sub-assemblies for aerospace and defense, industrial, automotive, and motorsport applications, such as:<\/p>\n\n\n\n<ul class=\"three-col wp-block-list\"><li>KERS \u2014 Kinetic Energy Recovery System, which includes a composite sleeved RECOMA\u00ae SmCo magnet rotor for a 50,000+ RPM, 100KW+ system<\/li><li>Electric Turbo Charger \u2014 Inconel or composite sleeved RECOMA\u00ae SmCo magnet rotor incorporating Arnon Silicon Steel thin laminations that operates at &gt; 100,000 RPM<\/li><li>High Power Density Cabin Air Pressure Motor \u2014 Inconel-sleeved RECOMA\u00ae SmCo balanced rotor, which is part of 180KW system that operates in excess of 200\u00b0C.<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">HIGH-SPEED PERMANENT MAGNETIC ROTOR ASSEMBLIES<\/h3>\n\n\n\n<p>High-performance electric machines are characterized by their rotational speed, system efficiency, power density, and ability to function in extreme conditions. Typically operating in excess of 50,000 revolutions per minute (RPM), these electrical machines run faster and hotter while achieving higher efficiency in a smaller package.<\/p>\n\n\n\n<p>Arnold also
