Torque vs microsteps

Hi Everyone,

Drivers A4988, DRV8825 and others, what is the relationship between microsteps and torque for the stepper motor? Is there any estimated efficiency in relation to increasing the number of microsteps?

Thank you for your help!


Microstepping significantly reduces how much torque a stepper motor can apply per microstep. Here is an application note with more details about that.
