One kind of equipment needs a stepping motor. Ask how to calculate the required torque.

The information you provided is not enough to calculate the torque. Usually, you need to know at least the orientation of the screw, such as whether it is horizontal or vertical, or how much angle it is inclined, how much load it is, how much lead it is, and so on. If necessary, you can contact our company, and we will calculate the parameters related to the selection and recommend the appropriate model products for you. Baidu Q&A should not let you leave your contact information directly.
