Calculate torque of electric motors

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

Md = 9550 x P / n

Here is an example:

A standard three-phase AC motor has a rated speed of 1420 revolutions
and a mechanical output at the motor shaft of 15 kW.

What is the torque of the motor at rated speed?

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

Md [Nm]=100.88 Nm

For your information: The calculator is only suitable for electric motors without gearboxes!
