Abstract:
A commutator 10 for an electric motor comprises a plurality of commutator segments supported by a base. The segments have an electrically conductive body portion 14 and at least one electrically conductive foldable tang 16 provided on the body portion 14 for engaging a winding lead wire 44 of an electric motor. The foldable tang 16 has a proximal end 18 on or adjacent to the body portion 14, and a distal end 22 remote from the proximal end 18. A wire-accommodating portion 30 is provided on or adjacent to the foldable tang 16, so that, when the tang 16 is folded, the wire-accommodating portion provides a predetermined gap 56 for the winding lead wire 44.
