We've used leadscrews in our linear motion applications for years because they give us high stiffness, very acceptable backlash and simplicity. As performance requirements increase, we're going to have problems with the leadscrew not accelerating quickly enough to high speeds. It looks like we have some torsional issues as well. Can we overcome this with better sending and control? Is it time to look to an electronic answer?
