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 a 24V voltage range, 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, an idle running current of 160mA, 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-degree clockwise positioning resolution (360°/4096). The system ensures reliable operation from -20°C to 80°C and provides comprehensive real-time telemetry feedback for position, speed, voltage, load, and temperature.
