Ultra-thin non-oriented electrical steel is a special silicon steel material with a thickness significantly lower than the conventional standard, typically referring to cold-rolled non-oriented silicon steel thin strips with a thickness ranging from 0.10mm to 0.20mm. Its core value lies in significantly reducing high-frequency eddy current losses through ultra-thin design, while also maintaining high magnetic permeability and high strength, to meet the strict requirements of high efficiency and lightweight for high-end equipment such as eVTOL (Electric Vertical Takeoff and Landing) motors and humanoid robot motors.
