Multiple Operating Modes
- Current loop mode: Control motor output power by controlling current.
- Position loop mode: Can control the angle of the hub motor in the range of 0–360 degrees.
- Velocity loop mode: Supports closed-loop speed control.
Supports RS485 Bus Communication
Only 1-Ch RS485 bus is required to control multiple direct drive servo motors at the same time.
* The robot chassis shown in the picture is not included.
Closed-loop Control, Multiple Feedback
You can get the motor feedback information such as temperature, position, velocity, current, etc. via communication.
Integrated Direct Drive Design, No Reducer
The integrated direct drive motor design allows the motor to provide smooth torque, steady speed and accurate position without an external reducer. Also features a compact structure and high integration.
Wide Speed Range Adjustable
The no-load speed of DDSM315 is up to 315±10RPM and operates at a rated speed of 200RPM with a rated torque of 0.55Nm, suitable for robotic projects that require high speed with reliable load-handling capability.
Waterproof & Dustproof, Longer Service Life
IP54 protection rating provides ingress protection against dust and water jets, extending the motor’s lifetime and performance.
Supports Suspension Installation
Can be installed with UGV suspension designed for hub motors using aluminum profile or side-mounted design. Simplifies chassis development.
* For reference only, UGV Suspension (A) and robot chassis are not included.
