Method of manufacturing a rotor coil and corresponding rotary electrical machine

摘要

A method of manufacturing a rotor coil (7) includes steps of - preparing a wire strand (31) bundling a plurality of wires (20a) and a reinforcing member (32) configured to reinforce the wire strand (31), - arranging the wire strand (31) and the reinforcing member (32) to bring an end (31a) of the wire strand (31) and an end (32a) of the reinforcing member (32) into contact with each other, the wire strand (31) being arranged to have a longitudinal direction perpendicular to a boundary (25) between the wire strand (31) and the reinforcing member (32) and to include the plurality of wires (20a) with an inclined longitudinal direction thereof on a first outer surface (F1) inclining with respect to the longitudinal direction of the wire strand (31) and - driving a rotating tool (30) along the boundary (25) on the first outer surface (F1).
