Rolling-ring drives are friction drives that convert the constant rotary motion of a plain shaft into a traversing action that moves an attached carriage. Used in positioning and reciprocating ...

Perhaps the most persistent nonsense in physics: the perpetual motion machine. Bad ideas come and go in physics. But there’s one bit of nonsense that is perhaps more persistent than all others: the ...

Using pulse outputs from a PLC is a cost-effective way to get simple motion. Most, if not all, PLC manufacturers provide a way to control servos and steppers using a pulse train signal. So when a ...
