DAMIAO H65-1EC Brushless Servo Joint Motor is a high-torque hub motor designed for demanding robotic and industrial applications. Featuring a modular driver-motor architecture, it allows seamless driver replacement without recalibration. The motor integrates a 17-bit high-precision encoder with ±0.05° accuracy, supports CAN FD communication, and offers real-time feedback of motion and thermal parameters. With 6 Nm rated torque and 21.5 Nm peak torque, it delivers powerful performance across 24V, 36V, and 48V systems, making it ideal for precision joint control in large-scale platforms.
