As several people mentioned it does look to be in some sort of delta configuration, 3 pairs of coils for six total windings. There are also some chips soldered to the inside back cover for the rest of the input wires, but I don't recognize any of them. There are three marked "6853 / D669" and one marked as "AUGN / 3175 / 529". The chips don't appear to be wired at all to the windings - could these be hall effect sensors or something for a feeback mechanism? I put some pictures on the web if anybody wants to take a peek. www.nerdulator.net/motor/ Now another question - is this not a stepper motor? I really don't care about the feeback mechanism right now, but I'd like to be able to get it spinning. Thanks to everybody for your help! -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY! [EE]:,[OT]: ->Other [BUY]:,[AD]: ->Ads
