Arnold Magnetic Technologies has developed a breakthrough in electrical steel technology that enables manufacturers to produce smaller, lighter, and more energy-efficient motors and generators. The company’s Arnon Non Grain Oriented Electrical Steel (NGOES) features optimized thickness and surface finish that significantly reduces energy-wasting eddy currents in high-performance applications.
Thinner Laminations for Superior Performance
Unlike conventional NGOES materials typically measuring 0.0118″ to 0.0185″ thick, Arnon NGOES is available in ultra-thin 0.004″, 0.005″ and 0.007″ gauges. This substantial reduction in material thickness proves particularly advantageous in high-frequency applications above 400Hz, where it counteracts eddy current effects and heat generation that typically plague high-speed motors and transformers.
Record-Breaking Efficiency Gains
The advanced material has demonstrated remarkable performance in real-world applications, with several motors incorporating Arnon NGOES achieving efficiency levels exceeding 98%. Comparative testing shows the thin laminations can reduce core loss by up to 50% compared to standard NGOES products, while also enabling more compact motor designs through improved power density.
Optimized for High-Frequency Applications
Arnon NGOES establishes new benchmarks for high-frequency operation, delivering superior performance in switching frequencies above 1KHz. The material’s uniform magnetic properties in all directions make it ideal for both rotor and stator laminations in demanding motor and generator applications where circular magnetic fields are essential.
Transforming Electric Motor Design
By addressing the fundamental limitations of traditional electrical steels, Arnold’s innovation provides engineers with new opportunities to push the boundaries of motor and generator performance. The combination of reduced energy loss, improved thermal management, and design flexibility positions Arnon NGOES as a transformative material for next-generation electric machines across industries.
