Hola Sebalejo,
Te copio lo que dice la Wiki en este link: [reprap.org]
Holding torque
Stepper motors do not offer as much torque or holding force as comparable DC servo motors or DC gear motors. Their advantage over these motors is one of positional control. Whereas DC motors require a closed loop feedback mechanism, as well as support circuitry to drive them, a stepper motor has positional control by its nature of rotation via fractional increments.
The Mendel officially requires approximately 13.7 N·cm torque (19.4 ozf·in) of holding torque (or more) for each of the X, Y and Z axis motors to avoid issues, although one stepper with less has been used successfully (see below). Recent designs for extruders (ExtruderController) almost exclusively require stepper motors as well, but no torque requirements have been given in those designs. If in doubt, higher is better.
For Wade's Geared Extruder (most widely used one as of 2012) it is suggested to use motor that is capable of creating a holding torque of at least 40 N·cm.
If you need to convert between different units for the torque you can use the torque unit converter.
Te recomiendo que todos los motores de tu máquina tengan por lo menos 40N·cm.
Cuando busques proveedores, te vas a encontrar con especificaciones del torque en distintas unidades de medida: N·cm, N.m, Oz·in.... para no hacerte lio podes usar esta pagina de conversion: [www.numberfactory.com]
