FEETECH FT5420M Servo Motor
FEETECH FT5420M Servo Motor
The FT-5420-C001 is a high-speed, 7.4V 20kg-class digital servo engineered with a high-performance coreless motor and an aluminum case for reliable heat dissipation. Designed for precise and agile motion control, it features ultra-durable steel gears with a 1/258 gear ratio, smooth dual ball bearings, and a standard 25T/5.9mm horn gear spline. Operating across a wide 4V-12V voltage range, this digital servo delivers a peak stall torque of 22.5kg.cm and a rated torque of 7.5kg.cm at 8.4V, achieving an impressive ultra-fast no-load speed of 0.095sec/60°. Driven by a pulse width modification command signal (500–2500 µsec) on a digital comparator, it ensures a highly accurate 180°±5° running degree with counterclockwise rotation, a dead band width of ≤4 µsec, and no mechanical limit angles. Weighing just 60.6±1g with a 30CM connector wire, it includes built-in smart electronic protection that automatically triggers after an 8-second stall, offering the perfect blend of swift responsiveness, high holding power, and structural safety for advanced robotics and high-end RC models.
