Given ω in = 1440 RPM ω out, target = 45 RPM T in, peak = 19.9 N·m N 1 (stage 1 driver) = 16 teeth N 2 (stage 1 driven) = 90 teeth N 3 (stage 2 driver) = 18 teeth N 4 (stage 2 driven) = 102 teeth η (per stage) = 0.98 dimensionless Solution Step 1 — compute each stage ratio, then multiply for the overall ratio: total = (90 / 16) × (102 / 18) = 5.625 × 5.667 = 31.875 Step 2 — at nominal motor speed of 1,440 RPM, divide input speed by the ratio: out, nom = 1440 / 31.875 = 45.18 RPM That lands within 0.4% of the 45 RPM target — close enough that belt speed will be 0.703 m/s rather than the design 0.700 m/s, which a peat conveyor will not notice
