Dear Dino10,

according to the common rules of winding declaration
A1 and A2 are for the armature winding
B1 and B2 are for the commutating winding
C1 and C2 are for the compensation winding
D1 and D2 are for serial field exiting winding
E1 and E2 are for parallel field exiting winding
F1 and F2 are for foreign (parallel)exited field winding.

It seems that this is a DC motor with almost all windings which are available.
I am sorry, but Im not a DC motor expert so may be the eglish wording is a little bit different.

If it is really an 3ph acinduction motor with two separate windings, the naming is wrong. Usually the declaration is U1-U2, V1-V2, W1-W2 for the first 3ph ac winding and U5-U6, V5-V6, W5-W6 for the second 3ph ac winding.

You have to meassure the resistance of each winding and if it is an 3ph ac induction motor there has to be once 3x the same value and second 3x the same resistance, but with adifferent value comparedto the first tripple.
I would recommend measssuring the values with a wheatstone resistor bridge.

Otherwise a photo of the motor and from the name plate will be helpfull.
