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 DDSM400 is up to 400±20 RPM, and is capable of operating at a rated speed of 100 RPM combined with a rated torque of 0.15Nm, suitable for robotic projects that require high speed running with low torque demands.
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
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, theUGV Suspension (B)and robot chassis are not included, please purchase separately. The open-source drawing of robot chassis is provided in the wiki.
