High Speed, High Efficiency Magnetic Rotor Assemblies

Stanford Magnets manufactures high-performance magnets, magnetic rotor 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 our advanced materials such as laminated magnets made with samarium cobalt or neodymium iron boron, and lamination materials.

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 more than 50,000 revolutions per minute (RPM), these electrical machines run faster and hotter while achieving higher efficiency in a smaller package. We produce high-performance motor components and sub-assemblies for aerospace and defense, industrial, automotive, and motorsport applications, such as Kinetic Energy Recovery System, which includes a composite sleeved SmCo magnet rotor for a 50,000+ RPM, 100KW+ system.

Electric Turbo Charger — Inconel or composite sleeved SmCo magnet rotor incorporating Silicon Steel thin laminations that operate at > 100,000 RPM.

High Power Density Cabin Air Pressure Motor — Inconel-sleeved SmCo balanced rotor, which is part of the 180KW system that operates more than 200°C. Turn to us for your next high-performance electric motor design challenge. Contact us to discuss your requirements.

To achieve performance goals, designers of high-performance electric machines must balance several challenges including:

  • 1. Thermal Management
  • 2. Increased Power Density
  • 3. Higher Speeds (100K+ RPM)
  • 4. Reduced System Weight
  • 5. Cost / Value Trade-off


Thank you for reading our article and we hope it can be helpful to you. If you want to know more about high-speed, high-efficiency magnetic rotor assemblies, or other magnet products, we advise you to visit Stanford Magents for more information.
