DESCRIPTION
The FEETECH FS5115M is a high-torque standard-size PWM servo designed for robotic arms, RC models, pan-tilt mechanisms, and other motion-control applications.
Operating at 4.8–6V, it delivers up to 15.5 kg·cm stall torque at 6V with a no-load speed of 0.16 sec/60° (62.5 RPM).
The servo features metal gears, a 25T output shaft, 180° rotation, and a nylon/fiberglass housing. Standard pulse-width control makes it easy to integrate with common RC receivers, microcontrollers, and robotics control systems.
With its combination of high torque, metal gearing, and standard PWM control, the FS5115M is suitable for robot joints, robotic arms, RC vehicles, pan-tilt systems, and DIY robotics projects.
