[TCML] Mot Help needed

Hi MOT folks,

 

I have 2 MOTS ready to submerge in a ammo box of transformer oil. It crossed
my mind that I may have a phasing issue. Clearly, on the 120/240 feed side,,
the winding on the inside needs to go to the other outer winding to series
them for 240 volt op. I plan to do a FW bridge so I believe I have to
disconnect the grounds at the cores. Do I have to take the output of one and
tie it to the internal winding of the other as in the LV phasing? This will
be stressful for both windings but I can't seem to get my head around if I
can connect the two inner turns. In the least this would create a reverse
mutual inductance if not null output.. In the scenario of traditional series
both inner cores will see the full 2200v. I guess this is ok under oil?

 

Lastly I have been wondering if I should remove the shunts. I'll probably
need to split the cores to get them out. This may be worthwhile as I may be
able to get some transformer paper under the cores designed for oil. I'm new
to the MOTley crew;-)
