Patent ID: 7342341

Claim:
A rotor for an electrical rotating machine comprising: a plurality of axial conductors; a rotor core having a plurality of axial grooves shaped to include a first element, and wherein the axial conductors are shaped to include a second element, wherein each of the axial conductors is disposed in and extends radially outward from one of the axial grooves, and wherein the first element and the second element interact to fix the axial conductors in the axial grooves with respect to centrifugal and torsional forces; and a third element disposed at a radially outward side of the axial conductors and between adjacent ones of the plurality of axial conductors and configured to keep the adjacent axial conductors at a predetermined distance and to stabilize the conductors in a circumferential direction, wherein a depth of the axial grooves is substantially smaller than a radial height of the axial conductors, wherein not more than one of the plurality of axial conductors is disposed in one of the plurality of axial grooves.
