ABSTRACT:
A commutator10for an electric motor comprises a plurality of commutator segments supported by a base. The segments have an electrically conductive body portion14and at least one electrically conductive foldable tang16provided on the body portion14for engaging a winding lead wire44of an electric motor. The foldable tang16has a proximal end18on or adjacent to the body portion14, and a distal end22remote from the proximal end18. A wire-accommodating portion30is provided on or adjacent to the foldable tang16, so that, when the tang16is folded, the wire-accommodating portion provides a predetermined gap56for the winding lead wire44.
