robyc:
I do know it has three wires and that there are 3 pairs of windings in a star formation:
Wire n.1 --> V winding --> V1 winding --> connection to U1 and W1
Wire n.2 --> U winding --> U1 winding --> connected to V1 and W1
Wire n.3 --> W winding --> W1 winding --> connected to V1 and U1
Oh, that makes it harder 
Each wire needs to be drive-able to positive, neutral, or negative. That needs something "better" than an H-bridge.
