A symmetrical pairing is made here so that two rotational emf devices are powered on the same axle rotation: but from the relative viewpoint of each sides 3 phase stator ring those sources of rotating magnetic flux are rotating oppositely as each opposite view of the rotation dictates. To compensate then the direction of the (DC) field current is changed oppositely on each rotating side by wiring them in series backwards to each other; which is actually the only possibility given the casing on both sides consists of the grounds for both of the fields on each side..A further double negative approach between the influence of field current direction related to rotational direction is shown. The verification of an initial remanent magnetic field and its removal by reverse field magnetization and the process of attempting to restore the former amount of remanent magnetization is shown. Bus Alternator Video Pt. 1 Dismantled bus alternator components and modification of symmetrically joining two bus alternators together with a common pulley for both. Each three phase system can also varied in timing between them to provide any needed phase angle between them, but here a test of that phase angle put identical to unity is made. Magnetek modification of changing the DC output to three independent delta phasing sources also shown. Two of of these are combined in series to obtain a wye output on both sides of operation and those wye outputs are then themselves combined in series. Three voltage meters showing the summation of the seriesed segments are shown to show voltage unity of each side of the three phase outputs. Experiment of a double reversal of both field currents and rotational direction is described and shown in pt 2.

View on youtu.be Preview by Yahoo Experiment of a double negative combination of both directions of pole face rotation and field current shows the remanent magnetism of the field rotor has become demagnetized, and now the voltage output shown at the beginning test of 2.5 volt field DC field magnetization no longer produces the better effect found at the beginning of the demonstration. Hence the field current is then doubled and shut off in attempt to regain the former amount of (correctly)magnetized field. Then it is tripled to make the "no field" former no field observations appear when bearing or offset pulley drive problems develop and the alternators must have the field influence removed. These tests are done at the slower speed of 600 rpm of a 6 pole face rotor making three cycles per revolution establishing ~ 60 hz stator output and the efficiency seems terrible as the field voltage input and stator voltage output are near identical. The pair is driven from a variable speed motor incorporating a Leeson variable frequency drive set at 20 hz equating to 20 revolutions/sec for both ends of alternators and input drive via equal pulley sizes.
