Overview
The FEETECH FT90M Servo Motor family is a micro digital PWM servo series with metal gears for robotics and embedded actuation. Models include FT90M (standard), FT90MR (360° continuous rotation), FT90M-FB (analog feedback), and FT90M-C012 (double shaft). All models use a pulse width modification command signal with a digital comparator amplifier and share compact dimensions and low current draw. See the full specifications below for exact, model-specific parameters.
Key Features
- Metal gear construction across FT90M, FT90MR, FT90M-FB, and FT90M-C012.
- Operating Voltage Range: FT90M/FT90M-FB/FT90M-C012 3–8.4V; FT90MR 3–6V.
- No load speed: 0.1sec/ 60degree @6V (FT90M/FT90M-FB); 100RPM @6V (FT90MR); 0.1sec/ 60degree(100RPM) @6V (FT90M-C012).
- Peak stall torque: up to 2.3kg.cm @6V (FT90M/C012); 2.15kg.cm @6V (FT90MR/FB).
- Rated torque: 0.76kg.cm @6V (FT90M/C012); 0.71kg.cm @6V (FT90MR/FB).
- Running degree: 280° (standard/FB/double-shaft) and 360° continuous rotation (FT90MR).
- Horn gear spline: 20T/3.95mm (FT90M/C012); 20T (FT90MR/FB). Horn type: Plastic, POM.
- Compact case: PC plastic (FT90M/C012) or ABS (FT90MR/FB). Connector wire lengths: 200mm (FT90M), 250mm (FT90MR/FB), 25CM (FT90M-C012).
- Core motor design; idle current as low as 6mA @6V; stall current 1000mA @6V.
- Dead band width: ≤4 μsec (FT90M/FB/C012); +/-25 μsec (FT90MR).
