9 apr 2024 · The Omni Calculator tool electric motor torque calculator can provide the torque for different rotating speeds, or you can do as follows: For the 1800 rpm case, apply the power, torque, and velocity relation: Power = 2 × 𝜋 × rpm × T / 60. Solve for T. Use Power = 1 hp and rpm = 1800 rpm. We get torque (T) = 3.96 N·m.
