Lightweight Robot Motion Unit

With 39 years of experience in lightweight motion control component development, Hangzhou Zhongda independently manufactures the Lightweight Robot Motion Unit, a lightweight robotic joint module designed for humanoid robots and collaborative robot applications. The product adopts an aerospace-grade aluminum alloy ultra-thin housing combined with a lightweight frameless torque motor. While maintaining rated torque output, the overall weight is reduced by approximately 30%, significantly improving the robot payload-to-weight ratio and meeting the requirements of next-generation lightweight robotic systems.

Our factory covers 16,000㎡ and employs 125 professional engineers and production specialists. With an independent R&D team, we continuously optimize the internal electromagnetic structure of the Lightweight Robot Motion Unit. Fully automated stator processing lines and precision assembly systems ensure stable mass production quality. The monthly production capacity reaches 30,000 units, and each module undergoes dynamic load testing before shipment. The products are manufactured according to international export standards with CE and ISO9001 certifications.

The Lightweight Robot Motion Unit integrates a mini servo drive, ultra-thin harmonic reducer, and high-precision encoder. The 24V low-voltage power system makes it suitable for human-machine collaborative equipment. All models include an 18-month complete warranty covering key components.

Before purchase, our engineers provide remote assistance for lightweight robot structure design, electrical drive selection, and communication protocol adaptation. Standard products are delivered within 7–14 days, while customized lightweight joint samples require 15–45 days. The MOQ starts from 50 units, and different torque models can be combined in one order. For large-volume purchases, flexible pricing solutions are available. Production progress photos and videos are provided throughout manufacturing, third-party inspection is supported, and products are shipped with moisture-proof export packaging and optional reinforced wooden cases.
