Hi, I want to use Arduino to control the motion of a stepper motor which connects to a lead screw to make a platform to move up and down with a constant linear speed of 0.212mm/s or 0.03mm/s. What motor driver can do this when combined with one Nema23 stepper motor and an Arduino?
Use any current limiting stepper driver that can handle the winding current, and step the motor at the desired rate.
You can try A4988 or DRV8825.
Without telling us the pitch of the screw and how many steps per revolution the motor is, you are unlikely to get a correct answer.
Nema 23 tells about the mechanical mounting, not useful for us.
The pitch is 8mm. I have not chosen the motor yet. Is 200 steps per revolution a standard for stepper? Will that do for my slow linear speed requirement?
Why did you state NEMA 23 mounting plate size?
Pick the motor according to the required power, torque and steps per revolution. 200 steps per revolution is common but there are many other possibilities. Torque and power are determined by the weight of the platform and load, and the upward speed of motion.
Then pick the current limiting stepper driver to match the motor current and voltage requirements. Pololu has the best selection.
Steppers don't have a voltage requirement as such. They have current, resistance and inductance. Low inductance will run faster for a given supply voltage. NEMA23's usually have a fairly high current requirement, often larger than a DRV8825 can source, but they do vary and its essential to have this data to make a decision.
Yes, NEMA 23 have higher current requirement which sometimes the DRV8825 cannot provide. In my case, I need at least 3A,. It looks like quite a few people in the community use TB6600. Is there anything special about it? How is it compared with the DQ542MA or other motor controllers? I want smoothness even at low speeds.
Unless you have a very high gear ration on the motor output shaft, you can only get STEP movements from a stepper motor!
