Here you have the possibility to calculate the torque of electric motors.
Md = 9550 x P / n
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!
