DAMIAO DM-S3519 BLDC Planetary Gear Motor with Integrated Driver

The DM-S3519 is a compact 42 mm BLDC planetary gear motor with an integrated driver and incremental encoder. It runs at a 24 V rated voltage (driver input 15–52 V supported) and delivers 3.5 Nm rated torque (7.8 Nm peak) with a rated speed of 395 rpm (max no-load 435 rpm). The controller supports MIT / Speed / Position modes, offers CAN bus control with UART (921,600 bps) for configuration, and includes comprehensive protections for safe, reliable operation. With a 1:19.2 planetary reduction, Ø42 mm diameter, 91.5 mm height and about 396 g weight, it fits tight spaces while providing high output torque.
