FEETECH SCS40 Servo Motor
FEETECH SCS40 Servo Motor
The SC-4000-C001 is a high-performance 8.4V 40kg serial bus smart servo engineered for robotic joints, educational platforms, and maker projects. Housed in a premium aluminum alloy case for optimized heat dissipation, it integrates a coreless motor, a durable metal gearbox, a 25T output shaft, and a high-quality potentiometer. Driven by Feetech’s self-developed TTL control board, this smart servo delivers a powerful 40kg.cm stall torque with a 300° effective control angle, while supporting dual working modes: standard servo mode and continuous rotation motor mode. It provides comprehensive real-time feedback on position, speed, voltage, current, temperature, and load parameters, enabling robust overload and over-current protection.
