This means some pretty high voltage will be exposed on commutator of the armature under test, so care should be taken when using one! Testing for shorts to the ground or the core of the armature ...

Both brushless and brushed motors do that, but brushless motors do it without two carbon brushes flanking what's known as the commutator. In a brushed motor, the armature, or the rotor that drives ...

Topics covered in this video: circuits, current, magnets, electromagnets, armature, commutator, brushes, stator, and rotor. This video only covers DC motors. Maybe I will cover AC motors in a ...
