FEETECH FS90R Servo Motor

The FS90R is a high-speed micro 6V 1.5kg-class 360-degree continuous rotation analog servo powered by an efficient metal brush motor and housed in a lightweight ABS case. Engineered for continuous motion, smart robotics, and wheel-driven platforms, it features durable plastic gears, a 21T horn gear spline, and tough plastic/POM horns with no mechanical limit angles. Operating within a 4.8–6V voltage range, this analog servo delivers a peak stall torque of 1.5kg.cm and a rated torque of 0.5kg.cm at 6V, while achieving a rapid no-load speed of 130RPM at 6V (and 100RPM at 4.8V). Controlled via standard pulse width modulation (900~2100 µsec), it executes clockwise rotation (CW at 1500~900 µsec) and counterclockwise rotation (CCW at 1500~2100 µsec) with a neutral stop position point at 1500 µsec. Weighing just 9.0±1g with a 250mm connector wire, it delivers a superior power-to-weight ratio and seamless endless panning control for micro RC vehicles, rolling robots, and DIY electronics kits.
