Arnold Magnetic Technologies Carbon Fiber Encapsulation Wraptite®

Arnold Magnetic Technologies offers composite and metallic encapsulation solutions for a wide range of permanent magnet systems and applications. While metallic sleeved magnet containment solutions are used extensively for magnet containment, Wraptite composite sleeves offer a superior design alternative for today’s higher performance applications in which rotational speeds exceed 50K RPM. In addition to RPM, Wraptite encapsulation is a perfect fit for systems that must operate reliably in extreme conditions while reducing system weight. Applications with these characteristics are found in automotive, motorsport, oil and gas, aerospace and general industrial systems. APPLICATION EXAMPLES KERS — Kinetic Energy Recovery System, which includes a composite sleeved RECOMA® SmCo magnet rotor for a 50,000+ RPM, 100KW+ system Electric Turbo Charger — Inconel or composite sleeved RECOMA® SmCo magnet rotor incorporating Arnon Silicon Steel thin laminations that operates at > 100,000 RPM High Power Density Cabin Air Pressure Motor — Inconel-sleeved RECOMA® SmCo balanced rotor, which is part of 180KW system that operates up to 170°C WRAPTITE MATERIALS OPTIONS Wraptite composite materials include carbon fiber, Zylon fiber and glass fiber composites using a range of epoxy, cyanate ester and BMI-based resin systems. Our technology includes the winding of multi-filament tows directly over the rotor to be contained, or the production of sleeves which are pressed into position to produce an interference fit.
