Permanent magnetic rotor

Arnold Magnetic Technologies manufactures high-performance magnets, magnetic assemblies, precision thin metals, and electric motor components and assemblies for highly efficient electric machines. Our engineers work with motor designers every day to optimize their rotor assembly designs using Arnold’s advanced materials such as L Type laminated magnets, permanent magnets made with RECOMA samarium cobalt or neodymium iron boron, and Arnon lamination materials. Our power-dense permanent magnet materials are lightweight which allow us to produce top quality, high energy efficient motors. SMALLER, FASTER & HOTTER DESIGN CHALLENGES In order to achieve performance goals, designers of high performance electric machines must balance several challenges including: Thermal Management Increased Power Density Higher Speeds (100K+ RPM) Reduced System Weight Cost / Value Trade-off HIGH EFFICIENCY MOTORS WITH POWER-DENSE PERMANENT MAGNET MATERIALS Arnold manufactures Recoma® 35E, the world’s most power-dense samarium cobalt material available on the market today. This innovative magnetic material is critical to boosting performance in the aerospace, automotive and motorsport industries, providing superior power density without adding weight. Arnold produces high performance permanent magnet motor components and sub-assemblies for aerospace and defense, industrial, automotive, and motorsport applications, such as: KERS — Kinetic Energy Recovery System, which includes a composite sleeved RECOMA® SmCo magnet rotor for a 50,000+ RPM, 100KW+ system
