• Supports RS485 bus communication
• Supports obtaining motor feedback information through communication such as position, speed, current, error code, etc.
• With Hall position detection, over-current protection, etc.
• Supports electric brake
• No drive mechanical friction, drive efficiency close to 99.99%

Specifications

Note: The above parameters were measured at the rated voltage of 18V DC.

Multiple operating modes

Current loop mode, position loop mode, velocity loop mode

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, but we provide its open-source drawing, please refer to the Package Content for detailed part list

Closed-loop Control, Multiple Feedback

You can get the motor feedback information such as temperature, position, velocity, current, etc. by 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 with the advantages of compact structure and high integration.

Wide Speed Range Adjustable

The no-load speed of DDSM315 is up to 315±10RPM, and is capable of operating at a rated speed of 200RPM combined with a rated torque of 0.55Nm, suitable for robotic projects that require high speed running with reliable load-handling capability.

Waterproof & Dustproof, Longer Service Life

IP54 protection rating, the ingress protection design against dust and water jets can make the motor better protected, provides longer lifetime and better performance

Supports Suspension Installation

Supports Installing with our UGV suspension designed for hub motors via aluminum profile or by cutting holes on the side of the chassis, reducing the difficulty of chassis design

* for reference only, the UGV Suspension (A) and robot chassis are not included, please purchase separately. The open-source drawing of robot chassis is provided in the wiki.
