Web12 mei 2024 · On some screws, the lead and pitch are the same: these are single start screws. A single-start screw has only one helical tooth running through it. You can tell how many starts a lead screw has by looking at its profile. On a multi-start screw, the pitch and lead are different: for example, a two-start screw with a pitch of 2 mm will have a ... Web12 apr. 2024 · To simulate the dynamics, I have created a Simscape model. I have coupled 3 lead screws (doing the proper translation and rotations to get the desired 'shape') and then, to try, I tried to make the stepper motor an input for the lead screw, as can be seen in the image, thanks to a Rotational Multibody Interface.
