DDSM400 Direct Drive Servo Motor

The DDSM400 is a direct-drive servo motor that combines an outer rotor brushless motor, encoder, and servo drive into one compact unit. This permanent magnet synchronous motor is easy to install and provides stable operation, making it ideal for a range of projects. With its small size and high-speed capability, the DDSM400 is ideal for direct drive needs, including powering wheels on small AGVs, balance vehicles, and advanced robotics projects focused on vehicle platform development.

Through optimised engineering, and adjustments in pole slots, geometry, air gap, and magnet materials, the DDSM400 has an impressive no-load speed of 400±20 RPM. For projects requiring high-speed rotation with low torque, it reaches a rated speed of 100 RPM paired with a rated torque of 0.15Nm. This makes it a perfect match for robotics projects needing precise and fast motion.
