CubeMars AK Series Dynamical Modular AK80-9 Motor

The AK80-9 Dynamical Modular Motor is an advanced integrated actuator developed for robotic systems that require precise movement, high torque, and responsive control. Manufactured by CubeMars under the T-Motor robotics platform, it combines a brushless DC motor, planetary gear reducer, magnetic encoder, and integrated driver board into a single compact module.

Operating at a rated voltage of 48V, the AK80-9 delivers 9N·m of rated torque and up to 18N·m of peak torque. Its 9:1 reduction ratio helps provide strong output torque while maintaining a rated speed of 390RPM.

The integrated Field-Oriented Control (FOC) driver supports precise motor operation, while the magnetic encoder provides position feedback for closed-loop control. CAN and UART communication interfaces allow integration with compatible controllers and robotic control systems.

The AK80-9 is suitable for robotic joint development, quadruped robots, exoskeletons, robotic arms, research platforms, and automation equipment.

How to Use

1. Check that your power supply supports the actuator's 48V rated voltage.

2. Mount the AK80-9 securely to the mechanical joint or robotic structure using the appropriate mounting arrangement.

3. Connect the motor power cable to a suitable power source.

4. Connect the CAN or UART communication interface to a compatible controller.

5. Configure the motor driver and communication parameters according to the CubeMars AK Series manual.

6. Select the appropriate control mode, such as position, speed, or torque control.

7. Test motor direction, encoder feedback, and communication at low output before applying higher loads.

8. Gradually tune the control parameters according to the mechanical system and application requirements.

Important Notes

• This actuator is designed for a 48V rated power system. Verify the power supply requirements before connecting it.

• Use a compatible controller and communication configuration for CAN or UART operation.

• Do not connect or disconnect motor wiring while the system is powered.

• Securely mount the actuator and ensure the connected mechanical structure can withstand its torque output.

• Avoid foreign objects entering the motor or gearbox assembly.

• Do not disassemble the actuator without appropriate technical knowledge, as this can affect encoder alignment and control accuracy.

• Operate within the specified environmental temperature range of -20°C to 50°C.

• Rated and peak torque are different operating limits. Do not treat peak torque as a continuous operating rating.

• Confirm the exact hardware revision and firmware compatibility before integrating it into a robotic system.
