Servo & Reducer Sizing — Welding Positioner Turntable
Motor torque through the reducer for a welding positioner turntable from load, speed and ratio.
Positioners carry awkward, offset fixtures, so their J varies wildly between jobs — size for the worst fixture, not the average. With i = 200 the motor barely notices the part, but the reducer feels every newton-metre: check its rated and emergency-stop torque both.
Formula
Note: Planning-level engineering estimate — final robot selection, guarding layout and risk assessment must follow the integrator's calculations and a documented ISO 12100/10218 risk assessment.

About Servo & Reducer Sizing — Welding Positioner Turntable
Servo & Reducer Sizing — Welding Positioner Turntable computes the governing relationship T_m = (J·α + T_static) / (i·η) · n_m = n_joint·i live as you type. Positioners carry awkward, offset fixtures, so their J varies wildly between jobs — size for the worst fixture, not the average. With i = 200 the motor barely notices the part, but the reducer feels every newton-metre: check its rated and emergency-stop torque both. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Servo & Reducer Sizing — Welding Positioner Turntable
- 1Enter your values — Load inertia at joint, Joint speed, Time to reach speed, Gravity/static torque at joint and more (sensible defaults are pre-filled).
- 2Read the live results: Peak motor torque, Acceleration share, Motor speed.
- 3Check the "with your numbers" line to see T_m = (J·α + T_static) / (i·η) · n_m = n_joint·i substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.

Frequently asked questions
What formula does the servo & reducer sizing — welding positioner turntable use?+
It evaluates T_m = (J·α + T_static) / (i·η) · n_m = n_joint·i, exactly as published. Sources: Nabtesco / Harmonic Drive sizing guidelines; Siciliano & Khatib (eds.), Springer Handbook of Robotics, 2nd ed.. The substituted worked example on the page lets you verify every step against the textbook.
How should I read the result — and how far can I trust it?+
Positioners carry awkward, offset fixtures, so their J varies wildly between jobs — size for the worst fixture, not the average. Planning-level engineering estimate — final robot selection, guarding layout and risk assessment must follow the integrator's calculations and a documented ISO 12100/10218 risk assessment.
