Cubemars AK80 9KV100 Brushless DC Motor for Robots

• High torque output
• Highly integrated design
• Suitable for exoskeleton and quadruped robotic dog applications
• UART and CAN interfaces

The Cubemars AK80 9KV100 Brushless DC Motor for Robots is a two-in-one dynamic module that combines efficiency and dynamics. It is highly integrated and has an ultra-light design, weighing only 485g and being as thin as 38.5mm. It provides low noise operation and strong power with a lower cogging torque and smooth running, as well as high resolution and precision control of up to 0.005 degrees. The motor is combined with a planetary gear solution that has a 9:1 reduction ratio, and features a plug and play design with a high integrated, high accuracy connector for optimized installation. This motor is ideal for applications such as legged robots, exoskeletons, and cobot arms.
