Innovative Applications of Electrical Steel in Humanoid Robotics
 – Powering Intelligent Motion

As artificial intelligence and robotics advance rapidly, humanoid robots are transitioning from labs to industrial, service, and healthcare applications, emerging as next-generation intelligent platforms. At the core of their agile movement, energy efficiency, and reliability lies electrical steel (silicon steel), a critical material for high-precision motors and drive systems.

Electrical Steel: The "Power Core" of Humanoid Robot Joints

Humanoid robots require compact, flexible drive systems to mimic human-like motion. Electrical steel, with its low core loss and high magnetic permeability, is ideal for servo motors, harmonic reducers, and joint modules:

Precision Servo Motors

Ultra-thin, high-grade non-oriented electrical steel (as thin as 0.15mm) minimizes core losses, enhances energy conversion efficiency, and ensures rapid joint response and extended operational endurance.

Optimized magnetic domain structures reduce eddy current losses under high-frequency operation, meeting stringent demands for instant torque and stability during dynamic adjustments.

Lightweight and Miniaturized Design

High magnetic flux density enables motor size reduction by over 30%, reducing joint module weight while enhancing agility and load-bearing capacity.
