Hi Troy, Something looks wierd on the picture. It looks like you have some starts going to tails and some starts going to starts then both tails to the bridge. ???? I'm I missing something? Thanks, RonD

We need to know the layout of the magnets, but I think you are right that there is something wrong here.

The coils will be in phase when the same magnet pole is on top of each at any given time. If they are in phase then you connect start to finish for series. And start to start for parallel.

Here it looks as if they are in phase at the neutral and at the tails (parallel, start to start), but when the series connection takes place it looks like the poles are different (start to start again in series).

It doesn't look right. But if you check as described in the text you will be OK.

The diagram would perhaps look more familiar if the coils were installed every other one clockwise, every other one counter clockwise. Then they can be wired in simple series fashion (start to end, start to end). But if they are all wound clockwise and all installed clockwise, then simple series connection will lead to voltage cancellation, thus the need to hook them up in serie as: start to start, end to end, etc.

Confusing, but I think correct. To be safe, check voltage as you hook it up.

best regards,

troy

I typically wind mine clockwise then the next counterclockwise and so on. I can see where the diagram could be a little confusing at first but in essence it is correct if your winding them all the same direction and making connections for every coil.

Lots of fun
