The resolution on the process is described via the linear length traveled for each the smallest rotational go achievable (this is probably not a Think about some layouts). A numerically small lead will provide greater resolution than a larger lead. When the lead screw assembly ought to resist motion when electric power is shed then it can not be backdrivable. The flexibility of the lead screw to backdrive is a function of the lead angle, thread geometry, and coefficient of friction. If a non backdriving lead is necessary the company with the lead screw really should be consulted as precise thread geometries may possibly fluctuate as will the coefficient of friction (materials dependent). The drive enter is usually a motor which is restricted by dimension, availability, budget, and out there enter electricity. As the application requirements are described, a clear overall performance concentrate on on the lead screw assembly could be developed.
