PROBLEM TO BE SOLVED: To provide a method of manufacturing a stator winding that can increase a coil occupation rate, the stator winding, a stator, and a rotary electric machine.SOLUTION: A method of manufacturing a stator winding includes: a winding process (S1) of winding a continuous conductor wire as many times as N rounds; a coil end part molding process (S2) of molding a plurality of coil end parts, projecting from an end face of a stator icon core while not housed in a slot, of the conductor wire of the N rounds wound in the winding process by using a plurality of molding tools arranged on a circumference; and a three-dimensional molding process (S3) of carrying out circular molding for molding the conductor wire circularly by moving all the molding tools radially with the coil end parts retained by the molding tools and slot housing part molding for molding a plurality of slot housing parts to be housed in the slot by moving adjacent molding tools axially in mutually opposite directions simultaneously in parallel wholly or partially. A coil occupation rate can be increased because of the three-dimensional molding.SELECTED DRAWING: Figure 1 |
