METHOD OF MANUFACTURING ROTOR COIL AND ROTARY ELECTRICAL MACHINE

摘要

A method of manufacturing a rotor coil of to an embodiment includes preparing a wire strand bundling a plurality of wires and a reinforcing member configured to reinforce the wire strand; arranging the wire strand and the reinforcing member to bring an end of the wire strand and an end of the reinforcing member into contact with each other, the wire strand being arranged to have a longitudinal direction perpendicular to a boundary between the wire strand and the reinforcing member and to include the plurality of wires with an inclined longitudinal direction thereof on a first outer surface inclining with respect to the longitudinal direction of the wire strand; rotary driving a tool at the boundary on the first outer surface so as to enter the boundary; and moving the rotary driven tool on the boundary along the first outer surface.

1. A method of manufacturing a rotor coil, comprising:
preparing a wire strand including a plurality of wires and a reinforcing member configured to reinforce the wire strand, each of the wires being bundled to form the wire strand; arranging the wire strand and the reinforcing member to bring an end of the wire strand and an end of the reinforcing member into contact with each other, the wire strand being arranged to have a longitudinal direction perpendicular to a boundary between the wire strand and the reinforcing member and to include the plurality of wires with an inclined longitudinal direction thereof on a first outer surface inclining with respect to the longitudinal direction of the wire strand; rotary driving a tool at the boundary on the first outer surface so as to enter the boundary; and moving the rotary driven tool on the boundary along the first outer surface.
