Motor torque calculator

The motor torque calculator calculates the motor rated torque from rated power and rated speed. See also Motor speed calculator.

Motor rating (kW)

Motor speed (RPM)

Motor rated torque: 98.83 Nm


The motor toque T in N.m is calculated with the following equation:

\(T=\displaystyle \frac{60}{2\pi}\cdot \displaystyle \frac {P \cdot 1000}{n}\)



Motor rating (P): Motor rating in kW.

Motor speed (n): Motor speed in RPM. The motor speed for AC motors can be caculated with the Motor speed calculator.
