Description
Specifications

The DDSM400 direct drive servo motor is based on an integrated development concept, combining an outer rotor brushless motor, encoder, and servo drive into a highly reliable Permanent Magnet Synchronous Motor (PMSM). It features a compact design, easy installation, and stable operation. Its small size and high speed are particularly suitable for the following direct drive applications: driving wheels for small AGVs, driving wheels for balance vehicles, and high-end robotics projects for developing vehicle platforms.

Through the optimization of the number of pole slots, geometry, air gap, permanent magnet materials, etc., the motor is guaranteed to have a speed of up to 400±20RPM in the no-load state, and can rotate at a rated speed of 100RPM combined with a rated torque of 0.15Nm, which can be used for robot projects that require high-speed rotation and low torque requirements, providing users with high-performance direct drive application solutions.

The motor is compatible with a driver that utilizes the Field Oriented Control (FOC) algorithm, combined with high-precision sensors integrated into the motor, achieving precise control over the motor and better noise reduction. The driver has a complete and reliable motor OBD (On-board diagnostics) monitoring mechanism and protection function to ensure the safe and reliable operation of the motor. At the same time, Waveshare provides an open source four-wheel drive off-road vehicle structure model for this model of direct drive servo motor.

Key features

Ultra low noise
High precision and zero-backlash
Fast response, direct drive without delay
Integrated motor and driver, compact structure and high integration
Provides smooth torque, steady speed and accurate position without an external reducer
Supports LIN bus communication, only 1-ch LIN bus is required to control multiple direct drive servo motors at the same time
Supports obtaining motor feedback information through communication such as position, speed, current, error code, etc.
Multiple operating modes: current loop mode, position loop mode, velocity loop mode
Supports the installation of Waveshare’s UGV suspension, designed for hub motors via aluminum profile or by cutting holes on the side of the chassis
With Hall position detection, over-current protection, etc.
Supports electric brake
Waterproof & dustproof: IP54 protection rating, the ingress protection provides a longer lifetime and better performance
No drive mechanical friction, drive efficiency close to 99.99%
