Classification: CPC H  Y | IPC H

Claim 5:
6. The apparatus for manufacturing a rotating electric machine as set forth in claim 1, further comprising a current controller configured to control the amplitude of electric current supplied to the coil when the magnet section is magnetized,
wherein
before being magnetized, the magnet section has easy axes of magnetization oriented in an arc shape such that at the locations closer to the d-axis, the directions of the easy axes of magnetization are more parallel to the d-axis than at the locations closer to the q-axis, and
the current controller is configured to:
supply, after the magnet section to be magnetized is arranged to face the magnetizing yoke, a predetermined first current to the coil and thereby adjust the position of the magnet section in the circumferential direction; and then
supply a second current, which is higher than the first current, to the coil and thereby complete the magnetization of the magnet section.
