Linear Motors - October 2016
The article "Linear Motors" appeared in the October 2016 issue of Power Transmission Engineering.
When the need arises for linear motion or positioning, there are many choices. One can use an Acme screw, ball screw, rack & pinion, or belts. The cost of a linear motor solution is generally greater than a mechanical linear product, but when one needs highly accurate, repeatable, high-speed motion, then the answer may be a linear motor.
