DDSM115 Direct Drive Servo Motor, Low Speed & High Torque, Low Noise, All-In-One Design, Hub Motor
DDSM115 Direct Drive Servo Motor
Adopts advanced direct drive technology, remove the reducer in the traditional drive
solution. Say goodbye to the shortcomings of expensive, noisy, inefficient and bulky
All-in-one Robot Joint
Based on the integrated development concept, DDSM115 is a high-reliability Permanent Magnet Synchronous Motor (PMSM) integrating outer rotor brushless motor,
encoder and servo.
Features At A Glance
- Ultra low noise
- High precision and zero-backlash
- Fast response, direct drive without delay
- Integrated motor and driver, compact structure and high integration
- Support RS485 communication mode
- Motor feedback information such as position, speed, current, error code, etc. can be obtained through communication.
- With Hall position detection, over-current protection, etc.
- Support electric brake
- No drive mechanical friction, drive efficiency close to 100%

Current Feedback
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 with the advantages of compact structure and high integration
Excellent Low Speed Performance
Compact, Yet Powerful
The DDSM115 speed is as low as 1 RPM and its torque up to 2.0Nm
Waterproof & Dustproof, Longer Service Life
IP54 protection rating, the ingress protection design against dust and water jets can make the motor better protected, provides a longer lifetime and better performance
