Here you have the possibility to calculate the torque of electric motors. 


Md = 9550 x P / n
Torque: Md
Power: P
Rotational Speed: n
Please fill all mandatory inputs.

For Example:

A standard three-phase motor has a nominal speed of 1420 revolutions
and a mechanical power on the motor shaft of 15 kW.

What is the torque of the motor at the rated speed?

                   9550 * 15 kW
Md [Nm] = ------------------
                   1420 rpm

Md [Nm] = 100.88 Nm


Important: The calculator is only suitable for electric motors without a gearbox!
