    Formulas

    Torque
    T [N·m] = 9549 · P [kW] / n [rpm]
    Gearbox output
    n₂ = n₁ / i T₂ = T₁ · i · η

    Note

    For gearbox selection, multiply the calculated output torque by a service factor for the application (shock load, daily operating hours, number of starts) and compare it with the gearbox catalogue rating.
