Thanks for the pictures. The chip with the funny little 'A' symbol is
definitely an allegro hall effect sensor for commutating. I'd have to look
up the others but I'd bet they're hall effects too. But they might be
intended for position feedback instead of traditional commutating.

It's definitely a three phase brushless.

I did get one thing wrong though, it's not a Delta configuration, it's a
"wye". Notice only one end of the coils attach to the ckt bd, the other
ends are connected together (upper left corner of motor2.jpg).

Allegro (www.allegromicro.com) is probably the best place to start looking
for brushless motor control information.

Good luck
