Chengdu Leen Automation Technology Co., Ltd. - 成都乐恩自动化技术有限公司

Chengdu Leen Automation Technology Co., Ltd. is a servo-control systems developer headquartered in the Jinniu District of Chengdu, Sichuan Province, China. Founded in 2016, the company designs, manufactures, and sells servo drives, servo motors, servo controllers, joint motors, and related motion-control hardware, positioning servo-drive technology as its core competency. According to the company's own profile hosted on the Chinese industrial-automation portal China Transmission Network (chuandong.com), which cites the company's official website at www.leenmc.com, Leen's products are characterized by small size, high power density, fast dynamic response, and full domestic sourcing of hardware and software components, along with strong environmental adaptability for demanding operating conditions.

The company's product range includes the MSL3N5R and GSL3N3R series of low-voltage servo drives, together with the LESG series of harmonic reducer motors, the LEPG series of planetary reducer motors, and the LERV series of cycloidal reducer motors, which function as integrated joint modules combining a drive, motor, and speed reducer for robotic and mechanical actuation applications. Leen states that its products are used across aerospace, satellite communications, specialized military equipment, marine vessels, robotics, the nuclear industry, medical devices, and rail transit. Media coverage of the company has noted that Leen's early business traction came from military-oriented motion-control applications such as gun and artillery positioning systems, with the company later broadening into nuclear, oil-and-gas, and wind-power motion-control applications.

Leen has raised outside capital to fund this expansion. Public reporting describes an angel round backed by Chongqing Binyu Technology Development, followed by a Series A round of several tens of millions of RMB completed in 2024 with participation from Oriental Fortune Capital. The company's contact channels listed alongside its official website include a toll-free service line and a general-purpose company mailbox, and its address is given as the 10th floor of Building B, Xingpu Center, No. 99 Zhenxing Road, in Chengdu's Jinniu District.

At the World Robot Conference 2026, Leen exhibited its joint-module and servo-drive product lines, which the conference's own exhibitor listing described as spanning four families of harmonic, planetary, cycloidal, and axial-flux joint modules together with aerospace-grade, military-grade, medical-grade, and industrial-grade servo drives, targeting specialized robots and unmanned aerial vehicles as end applications. This positions Leen as a component-level supplier of motion and actuation hardware into China's broader robotics and specialized-equipment supply chain rather than as a maker of complete robot systems.
