ABSTRACT:
The invention provides an insulator for insertion in an armature core slot of a motor and for preventing an electrical connection between the core and wire wound in the armature core slots. The insulator includes, when it is mounted in an armature core slot, a first end aligned with an end of the core that faces a commutator included in the armature, and a second end aligned with the opposite end of the core. The insulator further includes a tab extending from the second end of the insulator. The tab is bent to prevent movement of the insulator in the slot and toward the commutator. The insulator optionally includes another tab extending from the first end of the insulator. The optional tab is bent to prevent movement of the insulator in the slot and away from the commutator.
