摘要： At least part of each bridge portion (22) is heated and molten to form a keyhole (6), and a nonmagnetic element (81) is disposed around the keyhole (6). Thus, even when the width of the bridge portion (22) in the radial direction is increased, the bridge portion (22) is demagnetized. Therefore, leakage flux in the bridge portion (22) is reduced, and the output power of a motor is increased. Moreover, by increasing the width of the bridge portion (22) in the radial direction, the strength of the bridge portion (22) is increased, and breakage of the bridge portion (22) due to a centrifugal force at high-speed rotation of a rotor (1) is prevented.

摘要： Non-holding portions (11) of a holding ring (10) are demagnetized by supplying a nonmagnetic element to the non-holding portions (11) while melting the non-holding portions (11) by the application of heat. Each non-holding portion (11) is demagnetized such that, from the melting center toward each melting end portion thereof, the material of the non-holding portion (11) moderately changes from a nonmagnetic material to a ferromagnetic material. The permeability moderately changes, and hence generation of cogging torque during rotation of a rotor is suppressed.

摘要： Teeth coupling portions (22) of a ring-shaped teeth member (2) are demagnetized by supplying a nonmagnetic element to the teeth coupling portions (22) while melting the teeth coupling portion (22) by application of heat. Then, an inner peripheral portion of the ring-shaped teeth member (2) is pressed radially outward. Therefore, it is possible to plastically deform the teeth coupling portions (22) easily, so that the ring-shaped teeth member (2) and a ring-shaped yoke member (3) are easily fitted together. Accordingly, there is provided a method for manufacturing a stator for a motor, in which the amount of leakage flux is reduced and which has favorable magnetic characteristics.
