Arnold Magnetic Technologies Component
High-Speed Permanent Magnet Rotor Assemblies
High-speed PM rotor assemblies using RECOMA SmCo or NdFeB magnets, L Type laminated magnets, Arnon laminations and Halbach arrays for machines above 50,000 RPM.
Description
Arnold works with motor designers to optimize permanent magnet rotor assemblies, addressing thermal management, power density, higher speeds (100K+ RPM) and reduced weight. It also manufactures Halbach arrays.
Key features
- L Type laminated magnets, RECOMA SmCo or NdFeB magnets
- Arnon lamination materials
- Halbach arrays
- Typical speeds in excess of 50,000 RPM, up to 100K+ RPM
- Examples: composite-sleeved RECOMA rotor for a 50,000+ RPM, 100 kW+ kinetic energy recovery system; electric turbocharger rotor above 100,000 RPM; Inconel-sleeved rotor in a 180 kW cabin air pressure motor operating above 200°C
Applications
High-speed motors and generators, energy recovery systems, electric turbochargers and cabin air pressure motors.
