dc electric motor question

[crutschow]

I noticed in the data they mention series wound. Do you think there could be taps on the field winding or more that a single field winding for speed, even though the data doesn't mention multi speed?

That's a good thought.

With all of them apparently are common to the White wire, then the only option would be to use one field winding, or connect the two in parallel (if indeed there are two windings).

ok, this post was too confusing to leave up... see below for wiring diagram...

In the diagram, i drew all white wires with an orange marker for visability...

White to Blue = 8.1 Ω
White to Green = 8.1 Ω

Black to Blue = 17.1 Ω
Black to Green = 17.1 Ω

Blue to Green =15.5 Ω
White to Black = 9.9 Ω


Hopefully these resistance tests should help interpret the attached diagram...
