YiAxis Actuators' 6 Core Technical Advantages

YiAxis integrated 4-in-1 robotic joint module architecture

Ultimate 4-in-1 Integration

A seamless fusion of a brushless motor, harmonic reducer, dual encoders, and FOC driver. This all-in-one architecture minimizes footprint and maximizes integration efficiency for complex robotic systems.

High torque density robotic actuator up to 762Nm torque

Peak Torque Density (Up to 762N·m)

Engineered for high-load performance, our actuators deliver breakthrough peak torque with an exceptional power-to-weight ratio, specifically optimized for humanoid hips and knees.

YiAxis 20-bit absolute encoder for micron-level precision

20-bit Micron-Level Repeatability

Equipped with dual 20-bit absolute encoders, the YR-Series achieves an industry-leading ±0.001° repeatability, ensuring zero-backlash motion for surgery-grade precision.

YRC series side-exit cabling interface for robot joints

Innovative Dual-Exit Cabling Interface

Featuring our proprietary side-exit and rear-exit interfaces, the YRC series solves the complex internal wiring challenges in humanoid limbs, drastically reducing axial space requirements.
