Yes, it's pretty clearly brushless DC, since it's driven by an H-bridge and has the Hall-effect position sensor. But as you say, it's still 3-phase, just square

Yes, it's pretty clearly brushless DC, since it's driven by an H-bridge and has the Hall-effect position sensor. But as you say, it's still 3-phase, just square rather than AC sinusoids. A description of brushless DC control is here: http://www.nxp.com/files/microcontrollers/doc/app_note/AN4058.pdf http://www.nxp.com/files/microcontrollers/doc/app_note/AN405...
