Rectifier circuit for AC sources with 180˚ phase offset

[Manuel12]

In a simple 2-phase generator that I am making, I have 2 pairs of oppositely placed copper coils in arrangement similar to this:

I would like the generator to power DC devices. My question is: How could one rectify the output from opposing coils? Or, in other words, how could you rectify 2 AC outputs with an 180˚ phase shift?

I would expect the windings at 90° would have phase at 90°.
You need to show the rotor magnetic poles.

Opposite coils would have phase at 180°, so would be connected to sum the voltages.
For 180°, reverse the connections, or wind the coil backwards.
Use two full-wave bridge rectifiers, connect the DC outputs in parallel.

By winding the coil backwards, do you mean winding opposing ones in opposite directions to each other? Just want to check.

You are now aware that voltages can add or subtract, depending on how you wind or connect the coils.

How many North poles are there on the rotor?
How many South poles are there on the rotor?

One north pole on one half of the cylinder, one south pole on the other

 

[Baluncore]

One north pole on one half of the cylinder, one south pole on the other

The output of the windings will be in quadrature, which means 90°.

You are building a two phase alternator with four wires going to the rectifiers.
