FEETECH SM45BL Servo Motor, 24V RS485 Bus, Brushless, 45kg.cm Peak Torque, 70RPM, 12-bit Encoder, Aluminium Case

Overview

The FEETECH SM45BL Servo Motor (model SM-45BL-C001) is a 24V RS485 serial bus servo designed for robotics and automation. It combines a brushless motor, steel gear train (353:1), and dual ball bearings in an aluminium case and horn. A 12Bits magnetic encoder (360°/4096) enables precise control and feedback of position, speed, voltage, load, and temperature. Communication is half duplex asynchronous serial over RS485 with ID range 0–253 and 38400bps ~ 1 Mbps. Peak stall torque is 45kg.cm@24V with a no load speed of 0.142sec/60degree (70RPM). Operating temperature is -20℃～80℃ with storage -30℃～80℃.
