We just wrapped up a webcast that discussed the differences between stepper motors and servo motors, and how to make the right choice for driving a linear actuator. We had two users discuss their particular applications and the product manager from Bimba helped explain the technology.
Spoiler alert: you do have to register for it, and the folks at Bimba will be in touch to see if they can help with an application, but it's a pretty useful presentation.
It's available on demand at http://video.webcasts.com/events/putm001/42881/
