The DDSM315 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. 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 315±10RPM in the no-load state, and can rotate at a rated speed of 200RPM combined with a rated torque of 0.55Nm, 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, we provide an open source four-wheel drive off-road vehicle structure model for this model of direct drive servo motor, you can download the model and engineering files of the open source structure in the bottom "Resources" - "Open Source Structure".
