ROBSTRIDE06 QDD 36N.m integrated joint motor module
ROBSTRIDE06 is a 36 N.m peak-torque joint actuator with a compact 9:1 reducer. This quasi-direct-drive robot joint motor integrates a brushless motor, a 9:1 machined-steel reducer, FOC drive electronics and dual magnetic encoders in one assembly. It provides 36 N.m peak torque for transient motion demands within its electrical and thermal limits.The actuator uses a 48 V nominal supply and 1 Mbps CAN communication. Its 11 N.m rated torque is tested at 100 rpm with heat sinking. The 480 rpm +/- 10% no-load speed is a separate operating condition. ROBSTRIDE06 occupies the torque range between the 17 N.m and 60 N.m models. Its 480 rpm no-load figure and 11 N.m heat-sink-tested rating describe separate operating points, not simultaneous output.For robotic arms, legged-robot prototypes, education and custom automation, the integrated module reduces the number of separate drive components to package. Its 621 g +/- 3 g mass should be considered alongside load inertia, mounting stiffness and cooling when selecting a joint. The technical files below support CAD integration, CAN configuration and bench commissioning.

ROBSTRIDE04 is rated at 40 N.m with a 345 x 345 mm heat sink, or 35 N.m with a 220 x 200 mm heat sink. Peak torque and no-load speed are separate limits, not a simultaneous continuous operating point. Hardware OverviewMechanical InstallationCheck mounting-hole positions, screw engagement and output clearance against the drawing and the 3D model. Screws must not exceed the available housing thread depth.Power and CAN ConnectionsCheck supply polarity, CAN_H and CAN_L against the connector orientation before wiring. Establish the correct bus termination and unique motor IDs before multi-axis operation.Commission with conservative limits. Secure the mechanism, verify supply and CAN wiring, begin unloaded or lightly loaded, and stop motion before changing control modes. ApplicationRobot joint developmentBuild compact rotary joints for arms, legs, gimbals, and custom motion platforms. Compare the 36 N.m peak torque and 621 g-class mass against both smaller 17 N.m modules and larger 60 N.m modules before fixing the joint layout.Humanoid and quadruped researchPrototype controlled joint axes where integrated actuator packaging is useful. Evaluate the 9:1 reduction, mass distribution, acceleration torque and impact loading together. Validate each gait or movement cycle on a secured prototype before increasing the operating limits.Robotic armsDevelop shoulder, elbow, wrist, or gripper rotary axes for lab automation and manipulation research. Check the load moment at each arm position rather than using payload mass alone. The 11 N.m rated-torque conditions are important for sustained movement and holding tasks.Mobile roboticsIntegrate controlled rotary motion into AMR, AGV, inspection robot, and mechatronic subsystems. Use the 48 V supply and CAN interface as part of the complete subsystem design. Verify cable routing, mounting stiffness and host-side stop behavior before autonomous operation.Education and trainingTeach actuator control, encoder feedback, FOC concepts, and joint tuning workflows. Explore feedback, current commands, velocity and position modes on a bench fixture. Start with the model-specific manual and keep motion limits conservative while learning the control workflow.Custom automationUse in low-speed high-torque fixtures, pan-tilt systems, haptic rigs, and test benches. For repeatable test fixtures and custom axes, log position, speed and current while tuning. Plan a suitable thermal path and motion duty cycle, and verify stop behavior before unattended use.

ROBSTRIDE 10P provides 42 N.m peak torque, a 25:1 reduction and 460 g +/- 3 g mass. Compare the supply voltage, encoder configuration, mounting and heat-sink requirements as well as torque.What distinguishes the ROBSTRIDE06 configuration?ROBSTRIDE06 occupies the torque range between the 17 N.m and 60 N.m models. Its 480 rpm no-load figure and 11 N.m heat-sink-tested rating describe separate operating points, not simultaneous output.What are the rated and peak torque figures?The peak torque is 36 N.m. Rated torque is 11 N.m at the 100 rpm test point. Heat sinking is required. Peak torque is a transient capability and must not be treated as a continuous holding rating.What power supply does it require?The nominal supply is 48 V DC. The linked user manual specifies a 15-60 V DC operating range. Size the supply, wiring and protection for the complete system, including voltage transients during braking.What encoder feedback and communication does it use?It uses dual magnetic encoders, 14-bit single-turn absolute encoder resolution and a 1 Mbps CAN bus. Check the model-specific command scaling and the installed firmware before integrating it with a host controller.Does the motor option include a debug board?The motor option contains one ROBSTRIDE06 actuator module and excludes the debug board. The Debug Board option contains one debug board accessory and no motor.Which control modes and software resources are available?The user manual covers current, velocity, position and operation-control workflows, along with host-software setup. Use a compatible CAN interface and the correct firmware protocol. The official Python CAN examples cover RS00-RS06 through Linux SocketCAN.Can it run continuously at peak torque?No. Peak torque is a transient output limit. Continuous operation depends on speed, winding temperature, heat sinking, ambient conditions and load cycle. Check the thermal and overload curves for the planned duty cycle.Is it suitable for outdoor or exposed installations?Do not assume this model has the sealed housing of ROBSTRIDE02-IP67. Select enclosure protection, cooling and cable protection for the installation and use a separately specified sealed model where required.What should be checked before mechanical integration?Check the 88 x 88 x 49 mm envelope, the exact mounting drawing, screw depth, output clearance and cable routing. Calculate gravity and acceleration torque, support the mechanism securely, and begin commissioning with conservative current and speed limits.
