FEETECH FT2811M Servo Motor

The FT-2811-C001 is a high-performance 6V 11kg.cm digital servo built with an aluminum case, metal gear, plastic POM horn type, and reliable ball bearings. Powered by a coreless motor, this no-limit servo features an operating voltage range of 4.8–8.4V, delivering a peak stall torque of 12.2kg.cm, a rated torque of 4.1kg.cm, and a no-load speed of 0.054sec/60° at 8.4V. Its electrical specifications include a stall current of 2.8A, a running current of 170mA at no load, and an idle current of 6mA. Utilizing pulse width modulation via a digital controller, it accommodates a pulse width range of 500–2500 µsec with a neutral position at 1500 µsec and a dead band width of ≤8 µsec. The servo supports a 180° running degree (at 500→2500 µsec) and operates counterclockwise (at 1500→2000 µsec). This compact servo measures 23mm × 12mm × 27.5mm, weighs 21.5±2g, and is equipped with a 25T/4.95mm horn gear spline and a 25±0.5CM connector wire.

Common use cases: Compact humanoid robot finger, wrist and ankle joints requiring 12.2kg.cm torque in a 21g package, educational robot platforms with standard PWM control, small RC models, and applications needing coreless motor responsiveness with metal gears across a wide 4.8–8.4V range.
