FEETECH SM45BL-C001 Servo Motor

The SM-45BL-C001 is an advanced 24V 45kg.cm RS485 serial control BUS servo equipped with a high-torque brushless motor and a 353:1 steel gear train. Housed in a durable aluminum case with dual ball bearings and a 25T (OD5.96mm) horn gear spline, this smart servo operates at 24V, delivering a peak stall torque of 45kg.cm, a rated torque of 15kg.cm, and a no-load speed of 70RPM (0.142sec/60°). It features a terminal resistance of 7Ω, a KM constant of 19kg.cm/A, a running current of 160mA at no load, and a stall current of 2300mA. Utilizing a half-duplex asynchronous serial communication protocol (RS485) supporting IDs from 0 to 253 and speeds up to 1Mbps, it integrates a 12-bit magnetic encoder providing precise 360° clockwise positioning resolution (360°/4096). The system ensures reliable operation from -20℃ to 80℃ and provides comprehensive real-time telemetry feedback for position, speed, voltage, load, and temperature.

Common use cases: Heavy-duty industrial robot arm joints requiring RS485 bus communication at 24V with brushless motor durability, precision automation end-effectors, collaborative robot (cobot) joints, large-scale humanoid robot hip and knee joints, and applications demanding 45kg.cm torque with 12-bit magnetic encoder accuracy over RS485 networks.
