Embedding mechanical motion subsystems into machines improves
performance and reduces cost.
If you build machines, you probably work with actuators and positioning stages every day. But do you truly get the best performance or lowest cost of ownership from these motion devices? The answer may not be what you expect.
All too often, engineers think of stages or actuators as just another item on the bill of materials. As long as the motion device nominally meets the desired positioning, force, payload, speed and cost requirements, it’s good to go.
With simple motion requirements, this approach to stage or actuator selection may yield acceptable results. However, machines with complex mechanical motion requirements will benefit from an embedded motion design strategy. Rather than a collection of electromechanical components, which may or may not work well together, embedded motion systems function as true plug-and-play machine subsystems.
Embedded motion systems are engineered to fit within a predefined physical space on a machine and tie into the machine’s motion control system, ready to accept commands from a top-level computer interface, control card or PLC. At their simplest, embedded motion systems may consist of little more than a stage or actuator that has been connectorized to make the drop-in installation easier. At their most complex, these motion subsystems extend from pinout to payload. They encompass not only the motion device itself but also everything it carries…
