Russ Huber Posted November 18, 2022 Share Posted November 18, 2022 (edited) If your brushed motor armature tests bad, don't flip your lid and send it off for rebuild without giving it a close look first. This armature belongs to a GE series G 6" BB mighty mouse fan. I have a table mount magnifying light and carefully examined the armature for opens. A few of the commutator segments had no continuity. After finding no evident opens I CAREFULLY checked the armature winding leads soldered to the commutator segments using a probe carefully lifting them to find 2 Commutator segment winding connections severed. I was fortunate to have enough winding to reattach them under the magnifying glass/light with solder and now the armature is once again fully functional and ready for action. 🙂 The solder aid stick is pointing out the 2 winding to commutator segment repairs.

Russ Huber Posted November 18, 2022 Author Share Posted November 18, 2022 (edited) One has to be careful not to use to much goop or solder as the armatures, like a blade, are balanced. Notice how the wires from the armature field from the factory disappear into an insulator and thread wrapping to connect to the commutator segment. With modern liquid tape used sparingly applied I achieved the same applications as the factory.
