1-7 coil spacing instead of 1-4

1-7 jumper spacing. hi guys. has anyone experimented with 1-7 coil spacing? this connection was commonly used in very low rpm 3phase motors to cut electrical noise produced because the poles were jammed so close together. instead of jumpers within the phase connected 1-4, they were connected 1-7 ( skip pole ) would this create any usable effect for gennys?

I don't believe the 1-7 connection has any effect in alternator windings.

Each coil will have an "alternation" or, half-cycle, generated into it in the order that the magnets pass it, in other words, either clockwise or counter-clockwise, so the phase sequence will be either a-b-c or a-c-b.

There are some magnet/coil arrangements that result in the three phase voltages being generated 60 deg out-of-phase.
In order to connect the phase windings in wye or delta the voltages must be 120 deg out-of-phase, and this somtimes requires the interchanging of the "center" phase leads.

Hi,

your post looks interesting.

I think that if we would make a really low RPM generator,
there would be problems to make it running smoothly.
Maybe the idea of yours would help.
Could you, please provide more info, what you mean?
A rough picture of the arrangement?
