I am trying to calculate the torque for the stepper motor I need in my system. I found out this question with a nice answer how to calculate the different parameters (Stepper motor won’t turn once loaded). However, looking in the nominal time for one step I found a contradiction.
From the provided formula one can conclude that decreasing the motor torque leads to smaller times. Also, having smaller moment of inertia leads to bigger times. Is that correct? In my understanding it is the oposite - smaller load should lead to faster times. I am asking that because in my system the moment of inertia is 0.00012 and I need to have nominal time for a step of about 0.01s. Trying to use the above equation leads to very strange values for torque.
