DDSM400 wheel servo - Waveshare 28626

Description

The DDSM400 motor utilizes Direct Drive technology, eliminating the need for gear reduction, which results in higher efficiency, lower noise levels, and zero mechanical backlash. Its integrated design—based on a brushless permanent magnet synchronous motor (PMSM), encoder, and built-in driver—makes the DDSM400 a compact and reliable solution for mobile and hobby robotics. It supports LIN bus communication and multi-range feedback (position, speed, current, temperature), making it suitable for applications requiring variable speed control and precise operation.
