Bob Skala of Interactive Instruments spoke with us about very large servo motors, wind tunnels, and staying current in tech.
The Wright Brothers by David McCullough
And a note from Bob:
Below is a link to a type of servo system that tries to simplify the interface to be more like a stepper. It integrates the driver and motor into a single package so you can treat it like a stepper with digital step and direction or serial commands. You get the smoothness, speed, accuracy and low power (when idle) of a servo but the servo motor, driver, and cabling are integrated into one magic box. You add a DC supply and simple control signals and you are all set. They came out with this to replace stepper motors. I haven’t used one yet but I hope to at some point.
