Enrico shows how his Infineon TLE94112EL motor controller shield can be put to work through a simple Arduino sketch.

To solve the problem without sourcing a new switch, [Jean-Noel] built his own Arduino based Dahlander switch. This consists of three relays that select the wiring configuration for each speed mode.

Big thanks to [Stephan Walters] for the tip. Of course if you prefer to speed things up by hardware rather than software, you can overclock an Arduino– with liquid nitrogen, even.

Great phase-locked loop motor control app note Related to my search for reduced motor noise (and thanks to all who have made suggestions – ‘scope avaunt this weekend), is a search for speed stability ...
