ouch. AC becomes DC then it becomes AC again. But we call it DC becuz...uh, it likes AC going into 3 phases but then it synchronises its whatzits to the quartz crystal oscillator .... and stuff.
ok that's beyond me. Like I said early, I'll trust in the designer's ability to do this. I do recall using the 'brushed' DC motors I had on my Teres that could run either off a wall-wart that converted AC to DC, or straight off a 12 volt battery (sized about like a large motorcycle would use). But obviously this little piece of tech you have is quite different.
Pretty cool, though.

If you think about it, the commutator and brushes are there to transform DC into AC so the motor can run. You need an alternating magnetic field otherwise the motor won't turn. Consequently, aren't all electric motors really AC motors?I've never studied electric motors and I'm just guessing. Perhaps I'm wrong! ;-)
Best regards,

Yes. That seems likely.....and I suppose to all those who have actually studied electrical motors it should seem like one of the fundamentals. I guess a little reading up on what makes electric motors work would be useful.
thanks,
