Motion Control

As this e-book demonstrates, however, it’s not just as simple as adding electric systems and having a more efficient operation. There are considerations about motor selection (servo vs. stepper, for example), motor sizing, the use of encoders and the availability and value in DC power for systems. As with every other system on the plant floor, effective use of electric motors and actuators is a product of precise engineering, a clear understanding of operational goals and an understanding of the potential—and limits—of electric systems.

The results, however, can be important, as we demonstrate in the final case study in this book. The coordinated use of small electric motors and actuators give amputees using prosthetics a more natural way of walking. The lightweight motors and actuators make the technology possible and practical, and the engineering is the key to its effective use.
