I am experimenting with using a stepper motor on a diy vertical axis wind generator. It has two coils inside (6 wire; 2 are centre tap). My question is: Can I tie two coils together and connect the other two across my bridge rectifier? Will there be phase cancellation, there by reducing power output? I want to try this because then I only need to run two wires up the tower. (I could thenrectify near the batteries).
