Overview

The FEETECH FT870B Servo Motor is a high-torque, 180-degree brushless servo for robotics and mobile platforms. It features titanium gears, ball bearings, an aluminum case, and a 25T/5.9mm output spline. Two variants are available to match different power rails: 7.4V-class with up to 75kg.cm peak stall torque and 12V-class with up to 70kg.cm peak stall torque. The control system is a digital comparator with a 500–2500 μ sec pulse width range and 1500 μ sec stop position.

Key Features

  • Two models: FT-870B-C001 (6–9V) and FT-870B-C002 (9–12.6V)
  • 180±5° travel; counterclockwise rotation (1500→2000 μ sec)
  • 4 Pole Brushless Motor with 1/356 gear ratio
  • Titanium gear train, ball bearings, aluminum case
  • High torque: up to 75kg.cm @8.4V (C001) / 70kg.cm @12V (C002)
  • No-load speed: 0.142sec/60° (70RPM) @8.4V (C001) / 0.263sec/60° @12V (C002)
  • 25T/5.9mm horn gear spline; connector wire 30±0.5CM
  • Operating temperature: -20℃～60℃; storage temperature: -30℃～80℃
