Conclusion: Powering Forward with the Right Partner
Selecting an electrical steel manufacturer requires balancing technical prowess, supply security, and alignment with sustainability mandates. For EV, renewables, or industrial electrification projects demanding precision materials, rapid prototyping agility, and deep application engineering, Huaxiao-Alloy offers a compelling partnership advantage. Contact our global technical team to optimize your next motor, generator, or transformer design.
GOES (Grain-Oriented) excels in static transformers due to directional grain alignment minimizing core loss in one axis. NOES (Non-Oriented) is isotropic, making it ideal for rotating equipment (motors/generators) where magnetic flux direction constantly changes.
Higher silicon content (typically 2.5%-6.5%) increases electrical resistivity, reducing eddy current losses. However, it reduces tensile strength and complicates stamping. Huaxiao-Alloy optimizes silicon gradients within laminations for balanced performance (e.g., 35HX270).
Thinner laminations (0.18-0.25mm) reduce eddy currents at high frequencies (EV traction motors often operate >400Hz). Huaxiao-Alloy’s precision rolling and advanced coatings enable ultra-thin laminations with minimal degradation during stamping.
