AMIAO S3519-1EC Brushless Servo Joint Motor is a compact geared actuator designed for precision torque control in robotic joints and automation systems. With a rated torque of 3.5 Nm and peak torque of 7.8 Nm, it delivers strong low-speed performance through a 1:19.2 gear reduction. The motor features a smart driver architecture that allows plug-and-play motor replacement without recalibration, and supports CAN FD communication with real-time feedback. Its incremental encoder, multi-mode control, and dual temperature protection make it a reliable choice for developers seeking high integration and flexible control.
