How to check for a good or bad armature

In this video you will learn how to properly test an armature. Their are 3 test that most be done to determine a good or bad armature.
These test are:
1) 180⁰ resistance test measures the resistance of the winding on the commutator bars at 180⁰ apart.
2) Bar to Bar resistance test measures each individual bar in a loop.
3) Bar to Ground resistance test is done to ensure that theirs no continuity from the commutator bar to the armature shaft.

Easy and simple explanation, thank you.

Do you can use used wires which were not damaged whan rewind new or repair stator or rotor ? And what will happen whan we made less coils on armature than before , example , if we have 170 coils is it possible make 85 coils with double wire size , if is 0,2 replaced with 0 ,4 mm ? Is it impossible ..because rotor or magnet field inside ? I did that and nothing, no reaction and I after that made more coils how much were been and nothing happen . And maby is problem old coils but I check and current flows through to stator and goes on brushes and on rotor but no rotation . What you think it can be a problem. I didn t have insulation so I used plastic between stator and his magnet , maby is that reason ? So if you know something , it will be nice to heard !

Nice video, you showing something interesting, many thanks. However, the music in the background is rather annoying.

[@IshiTechtronics2570]

Thanks much I appreciate for the feedback. It was a motor car with their sound system across from where I was.

Armature of which model drilling machine and model number replacing brand

[@IshiTechtronics2570]

It's a Drill Master 4½ angle grinder
