Our Review
The Flange Output Planetary Gearbox Nema23Nema34 Motor Reducer 400W 750W 1KW Servo Step-Down Reduction Precise Gear(for 110 Servo 19mm,0.209027777777778) delivers solid performance for its category. With Step Angle: 1.8 degrees (200 steps/rev), Rated Current: 1.0A per phase, Holding Torque: 59 Ncm, it covers the essentials that most makers and engineers need for their projects.
Mechanical performance was consistent in our testing. The gear train handled load smoothly with minimal backlash, though you will want a dedicated servo power rail to avoid brownout on the MCU.
Wiring was straightforward. Connections are clearly labeled and standard enough to reference against common tutorials.
For the price point, the Flange Output Planetary Gearbox Nema23Nema34 Motor Reducer 400W 750W 1KW Servo Step-Down Reduction Precise Gear(for 110 Servo 19mm,0.209027777777778) delivers what you need without unnecessary complexity. Recommended for hobbyists and engineers working on projects where motors & actuators components are essential.
What We Like
- High holding torque keeps position under load
