FEETECH FT90M-FB Servo Motor
FEETECH FT90M-FB Servo Motor
The FT90M-FB is a high-performance micro 6V 2kg-class digital servo engineered with a reliable core motor and a lightweight ABS case. Designed for highly integrated feedback control, it features robust metal gears, a 20T horn gear spline, and durable plastic/POM horns with no mechanical limit angles. Operating within a 3–8.4V 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 swift no-load speed of 0.1sec/60°. Driven by a digital comparator amplifier using pulse width modification (500–2500usec), it ensures an exceptionally wide 280° running degree with versatile CW/CCW rotating directions and a dead band width of ≤4 µsec. Crucially, it provides real-time position monitoring via feedback voltage (0.04V at 900usec, 1.65V at 1500usec, and 3.2V at 2100usec). Weighing only 12.5g with a 250mm connector wire, it delivers an optimal blend of smart voltage feedback and metal gear durability for smart robotics, closed-loop telemetry, and micro RC applications.
