Is the rotary synchronous to the line?  That is, are your breaks at the
45 degree points so all 4 per cycle are at the same voltage?

...there are 4 stationary electrodes at 90 mech. degrees, and 2 rotating 
electrodes at 180 mech. degrees of the full circle, giving a bang each 90 
electrical degrees as well. The phase is adjusted, in order to have 4 equal 
bangs of the same voltage, by means of a John Freau type phase shifter.
