Claim 0:
1. A rotor manufacturing method for manufacturing a rotor including a rotating support ring having an annular shape around a rotation axis, magnetic bodies provided alongside the rotating support ring in a radial direction, and a composite material that integrally restrains the rotating support ring and the magnetic bodies, the method comprising:
a first step of disposing the rotating support ring and the magnetic bodies to be arranged in the radial direction;
a second step of spirally winding the composite material around the rotating support ring and the magnetic bodies arranged in the radial direction as a core, the composite material being not cured and containing reinforcement fibers infiltrated with a resin that is not cured, in which a fiber direction of the reinforcement fibers is a longitudinal direction; and
a third step of curing the resin contained in the composite material,
wherein the rotor further includes a joint fitting for attaching a blade, and
in the second step, after the composite material is wound around the rotating support ring and the magnetic bodies at a portion before the joint fitting is disposed, the joint fitting is disposed and the composite material is wound around the rotating support ring, the magnetic bodies, and the joint fitting.
