When to Outsource: Plug-And-Play Motion Subsystems
Building motion actuators and stages from scratch forces designers to order, inventory, and assemble hundreds of parts. It also increases time to market and requires technicians and specialized production equipment. An alternative is to order preengineered motion devices. Stages and actuators are often just items on a machine’s bill of materials. If they deliver the right force, payload, posit...

A Finer Control of Linear Motion
For precise automated positioning, think stepper-motor-based linear actuators. Linear actuators essentially generate force and motion through a straight line. In a typical mechanical system, a device’s output shaft would provide linear motion using a rotary motor through gears, a belt and pulley, or other mechanical components. Trouble is, these components must be coupled and aligned. Worse ye...
