FEETECH FT90MR Servo Motor

The FT-90MR-C001 is a high-performance micro 6V 2kg-class 360-degree continuous rotation digital servo powered by an efficient core motor and housed in a lightweight ABS case. Engineered for continuous motion and wheel-driven applications, it features durable metal gears, a 20T horn gear spline, and reliable plastic/POM horns with no mechanical limit angles. Operating within a wide 3–6V voltage range, this digital servo delivers a peak stall torque of 2.15kg.cm and a rated torque of 0.71kg.cm at 6V, while maintaining a steady no-load speed of 100RPM at 6V. Driven by a digital comparator amplifier using pulse width modulation (900–2100 µsec), it supports counterclockwise rotation (CCW at 1500–2500 µsec) with a dead band width of ±25 µsec and a stop position at 1500 µsec. Weighing just 12.5g with a 250mm connector wire, it offers an exceptional power-to-weight ratio and seamless endless panning control for compact smart robotics, mobile wheel platforms, and micro RC vehicle builds.

Common use cases: Wheeled micro robot drive wheels, continuous pan camera platforms, micro RC car and tank track drives, conveyor belt mechanisms in educational kits, and any application requiring 360° continuous rotation with PWM speed control in a sub-13g package.
