Overview
The FEETECH FT83 Series Servo Motor family comprises three high-torque, digital PWM models—FT830BL, FT8346M, and FT846BL—built for robotics and motion control where durability and precise positioning are required. Each servo uses a steel gear train with ball bearings inside an aluminium case, a 25T/5.9mm output spline, and a 1/378 gear ratio. Control is via pulse width input (500~2500 μ sec), stop position at 1500 μ sec, and a dead bandwidth ≤4 μ sec. Operating temperature is -20℃~60℃ with storage -30℃~80℃. Model options include brushless or coreless motors and 180° or 360° running degrees.
