DescriptionThe Waveshare DDSM400 Direct Drive Servo Motor is a compact DDSM400 servo motor for RC car, UGV and robotics chassis projects. As a direct drive servo motor, it integrat es a permanent magnet synchronous motor, encoder and servo into a wheel-style hub motor package.The DDSM400 hub motor removes the traditional reducer, giving the drive a compact structure, fast response, low noise and high precision. In a LIN bus servo motor system, one controller can centrally control multiple motors and read feedback such as temperature, position, speed and current.With 400+/-20RPM no-load speed, 0.15Nm rated torque, 25.2V DC input, IP54 protection and suspension-installation support, this robot hub motor fits mobile robots, light UGV platforms, delivery robots and compact direct drive motor experiments.Features Direct drive servo motor design without an external reducer. Integrates outer rotor BLDC motor, encoder and servo in one hub motor unit. LIN bus servo motor communication for centralized multi-motor control. Current loop, position loop and velocity loop operating modes. Feedback for temperature, position, speed, current and error state. Hall position detection, over-current protection and electric brake support. IP54 waterproof and dustproof design. Supports suspension installation for robot chassis builds.
