FEETECH SM85CL-C001 Servo Motor

The SM-85CL-C001 is a high-performance 12V 85kg.cm serial control RS485 servo designed for precision industrial and robotic applications. Featuring a robust aluminum case, steel gears, dual ball bearings, and a coreless motor, this 215g servo delivers a peak stall torque of 85kg.cm and a rated torque of 28kg.cm at 12V, achieving a no-load speed of 37RPM (0.27sec/60°). Operating in both servo and motor modes, it supports a continuous 360° running degree with no mechanical limiters. The device utilizes half-duplex asynchronous serial communication (digital packet) with an ID range of 0–253 and communication speeds from 38400bps to 1Mbps. Integrated multi-feedback sensors provide real-time data on position, speed, voltage, load, and temperature, ensuring operational reliability within a temperature range of -20℃ to 70℃.

Common use cases: Heavy-duty industrial robot arm and shoulder joints requiring 85kg.cm torque with RS485 bus communication, large-scale humanoid robot hip and knee joints, precision automation end-effectors, collaborative robot (cobot) joints, and applications demanding maximum torque with coreless motor responsiveness and dual servo/motor operating modes.
