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 designs using Arnold’s advanced materials such as L Type laminated magnets made with RECOMA samarium cobalt or neodymium iron boron, and Arnon lamination materials.
Arnold manufactures RECOMA 35E, the world's most power dense samarium cobalt material available on the market today.
This innovative material is critical to boosting performance in the aerospace, automotive and motorsport industries, providing superior power density without adding weight.
What is a High Performance Electric Machine?
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.
Arnold produces high performance 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
- 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 in excess of 200°C.

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
