Creo que se trata de un "par cuadrático" :) Saludos

Understanding Variable Torque Requirements


How To: Select a Motor for an Application that has a Variable Torque Requirement

Many applications today require more sophisticated motion than simply turning a fan. Using the example of a conveyor – if the conveyor is unloaded, it will run at a fixed torque equal to the friction of the system, but as you add and remove packages from the conveyor the load constantly changes. In order to accurately select the best motor for variable torque application you should analyze each of the loads to determine the RMS (root mean square) torque required by the motor.

RMS calculations are a good way of determining the magnitude of a varying torque. The standard equation to determine the RMS torque is shown below.

Equation for RMS formula







Where:
•T = required torque
•t = time at torque

The accuracy of the calculation will depend on the size of the time slices. When searching for a motor for your appl

Por aquí, tal vez:
"Un voltaje reducido produce corriente reducida y par mecánico o torque reducido también: A cualquier velocidad, la reducción de corriente es proporcional a la reducción del voltaje. El porcentaje de reducción del par mecánico o torque es proporcional al cuadrado de la reducción del voltaje, así, ½ del voltaje produce ¼ del par mecánico, 2/3 del voltaje producen 4/9 del par mecánico, etc."

, if the load torque at standstill is T, the motor torque is 1.2T when the motor voltage is at its rated value, say V.
