So I see on FeeBay people selling custom wound pancake armatures and give the resistance, I guess for racing purposes.

 

Just how do you do this?

 

The reason I ask is because I have a lot of pancake armatures around, on plates loose, etc.

 

I'de like to be able to check see if they are alive without putting them in and out of a chassis set-up with brushes, etc.

 

Thanks!

Ohmmeter each coil with probes on a pair of commutator plates, like all DC motors.

You're also in luck I think, because those arms' relatively high resistance might mean that an inexpensive multimeter would give you useful information.
