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.

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.
