Dyson is famed among those paying attention, for being a good marketer, not a particularly brilliant designer. As a result, most of his kit does not
do anything particularly revolutionary, in that it uses already perfectly well understood science and engineering, to do relatively simple things,
rather than doing anything massively new.
Now, I haven't done a heap of research into this digital motor stuff, but what I would say, is that motors in electrically powered contraptions are
practically ALWAYS digital in some regard. Most electrical motors work by way of various parts of a machine being told whether to be on or off,
according to the necessities of the task they are attempting to perform. Whether its a computer controlled axis table on a milling machine, or a hand
held tool, whether its a complicated task or a relatively easy one, the motors are nearly ALWAYS digital to some degree, controlled according to ones
and zeros, open or closed connections, electrons either flowing or not as is necessary to get the job done. They might switch on and off thousands of
times per second, in order to get a thing spinning at tens of thousands of RPM, but its all about the ones and the zeros at the end of the day, so the
terminology here is marketing guff, in all likelihood.
Check out videos by AvE (Arduino versus Evil) on YouTube, for a useful, and absolutely hilarious look up the skirts of some of Dyson's prior output,
to see what I mean.
