Company Profile

Company Profile

SHENZHEN PICEA MOTION TECHNOLOGY CO., LTD (PICEA MOTION, formerly known as Shenzhen Han's Motion Technology Co., Ltd.) was founded in 2015. As a national high-tech enterprise focused on core components for robots, we specialize in the R&D, design, manufacturing, and sales of precision harmonic drives.

Since 2010, our core R&D team has been dedicated to fundamental research and technological development in high-precision harmonic drive. The team has successfully overcame the challenge related to non-standard double-arc tooth profiles, significantly improving key performance indicators such as load torque, transmission smoothness, and repeat positioning accuracy. These breakthroughs have enabled technological upgrades and widespread adoption of domestically produced harmonic drive.

Our products are widely used across various industries, including robotics, aerospace, medical devices, semiconductor equipment, and CNC machine tools, providing precise and stable power transmission solutions for high-end equipment manufacturing and cutting-edge technology sectors in the world.

Types of Gear Box

PMCG Series Harmonic Drive Cup Type: Input and output are coaxial, there is no backlash, and the PMCG Series' positioning and rotational accuracy are very good. Harmonic drive gear box is a cup-type harmonic drive.

PMHG Series Harmonic Drive Hat Type: The power drive gearbox has a conventional hollow flanging structure, is small in size, has zero backlashes, coaxial output and input, and has high positioning and rotation accuracy.

PMCD Series Harmonic Drive Cup Type: Ultra-flat harmonic drive (PMCD) strain wave gears feature outstanding positioning and rotational accuracy, is lightweight and compact, and is input and output coaxial.

PMHD Series Harmonic Drive Hat Type: The shorter Flexspline component set and the high capacity output bearing make up the PMCD-III harmonic waveform generator. There are 5 sizes and 4 ratios available.
