I have an e-motor that I thought was just a run-of-the-mill shunt-wound (run-of-the-mill except for being really large)... but when I measured the FIELD windings' resistance, I got about .6 ohms, and when I measured the ARMATURE resistance, I got about 30 ohms. Is it because my brothers put me in the clothes dryer (and turned it on) when I was little, or is that just perfectly backwards? (And yes, I'm sure the armature measurement is the armature... not just because of the giant "A"s stamped into the metal, but also because you can see the physical connection between the A terminals and the brushes.)

Thanks for any light you can shed, ETers. Maybe I'm gonna wind up doing armature weakening to make this one go fast...

And since this is tangent to ElecTraks themselves, I guess I should suggest responses off-line to my regular e-ddress, mhall maxmatic com... but I also guess that, unless I'm just backward anyway, the story might be interesting.

Best to everyone,
