With stepper driver we can start ramp with 1000 step/sec , ( 1msec/step) as you can rotate 90 degreed in 100msec at half-step , full current, bipolar driving, 24volts power supply and chopper method. You must pay attention to elastic return when press chuck onto object because if can't detect force on object it's easy go overall max motor torque.
I can't understand, why i can start with 1000 step/sec and not more? It's related to motor or driver?
This motor have rated voltage of 3,1v, i think it'll burn. What mean half-step? Also what is chopper method?
I'm thinking of getting some stepper motors for a project so I'm interested in this.
I don't understand @icio's reply.
@Yaro, can you explain why you need to know the acceleration? Are you concerned about how quickly the motor will get up to speed without losing count of the steps?
I'm not looking for extreme precision, but for high speed. I need to rotate an object that opposes the movement with friction, so i need to calculate torque necessary to rotate it and the torque necessary to rotate mechanical gripper(that have it's weight). I have the approximate time within i need to complete 90° rotation(130ms or less). Now i need to choose motor that fit this specifics.
I found different motors with high torque, but I need to know if I can rotate them with a high acceleration, doesn't matter rpm if the motors have very slow acceleration and i don't need to do complete rotations.
