Abstract
The following abstract will replace all prior versions of the abstract in the application: A conductor for an electric machine, and a method of making the conductor. The conductor includes two zones of higher electrical conductivity; and a zone of lower electrical conductivity. The zone of lower electrical conductivity comprises-includes an electrically conductive material having a plurality of discontinuities in the electrically conductive material to provide the zone of lower electrical conductivity with a lower electrical conductivity than the zones of higher electrical conductivity. The zone of lower electrical conductivity separates the two zones of higher electrical conductivity along a lengthwise direction of the conductor.

A conductor for an electric machine, the conductor comprising:
- two zones of higher electrical conductivity;
- and
- a zone of lower electrical conductivity with an electrically conductive material having a plurality of discontinuities to provide the zone of lower electrical conductivity with a lower electrical conductivity than the zones of higher electrical conductivity;
- wherein the zone of lower electrical conductivity is disposed between the zones of higher electrical conductivity, so as to at least partly separate the zones of higher electrical conductivity along a lengthwise direction of the conductor, so as to inhibit lateral current flow and to permit longitudinal current flow in the conductor to reduce eddy current effects.
A method of manufacturing a conductor for an electric machine, comprising:
- forming two zones of higher electrical conductivity;
- and
- forming a zone of lower electrical conductivity with an electrically conductive material having a plurality of discontinuities in the electrically conductive material to provide the zone of lower electrical conductivity with a lower electrical conductivity than the zones of higher electrical conductivity;
- such that the zone of lower electrical conductivity is disposed between the zones of higher electrical conductivity, so as to at least partly separate the zones of higher electrical conductivity along a lengthwise direction of the conductor, so as to inhibit lateral current flow and to permit longitudinal current flow in the conductor to reduce eddy current effects.
