摘要： In a magnetizing device and a magnetizing method, with respect to a fourth magnetic body, a first auxiliary coil allows passage of a diametrical inwardly directed first auxiliary magnetic flux caused by a first auxiliary magnetic field. With respect to a fifth magnetic body, a second auxiliary coil allows passage of a diametrical inwardly directed second auxiliary magnetic flux caused by a second auxiliary magnetic field.

摘要： A magnetizing device includes at least one coil unit that generates a magnetic field. The coil unit includes a support, a coil wound around an outer circumferential surface of the support, and a fiber reinforced resin. The fiber reinforced resin is wound around the coil to prevent deformation of the coil in a direction away from a central axis of the coil.

摘要： In a magnetizing device and a magnetizing method, by an auxiliary coil applying an auxiliary magnetic field to a rotor, among a plurality of magnetic bodies, in the case it is assumed that an auxiliary magnetic field is not present therein, a diametrical inwardly directed magnetic flux caused by the auxiliary magnetic field is made to pass with respect to a magnetic body for which there is a possibility of the magnetic body being magnetized in a direction opposite to a direction in which the magnetic body should be magnetized due to the passage of a leakage magnetic flux.

摘要： A magnetizing method applies, to a rotor including a plurality of magnetic bodies that are arranged in the circumferential direction of the rotor and are to be magnetized, a magnetic field in a radial direction of the rotor to magnetize the magnetic bodies. The magnetizing method includes a step of arranging a magnetizing coil near the outer peripheral portion of the plurality of magnetic bodies and a step of applying a radially outward magnetic field only to one of the magnetic bodies while applying radially inward magnetic fields to the plurality of magnetic bodies.
