DDSM115 direct drive servo motor adopts permanent magnet synchronous outer rotor structure, removing the gear reducer of traditional servo motors to eliminate backlash and reduce mechanical wear. It supports high-precision position and speed feedback via 4096 encoder. It can be widely used for robot articulated joints, AGV driving wheels, self-balancing robots, omnidirectional mobile platforms and robotic educational projects. It works well with Raspberry Pi, Jetson series and STM32 controllers for secondary development.
