Title:
回転電機の製造装置と回転電機の製造方法
Document Type and Number:
Japanese Patent JP7302399
Kind Code:
B2
Abstract:
A manufacturing apparatus includes a magnetizing yoke in which a magnet section to be magnetized is installed. The magnetizing yoke includes a core having slots formed at predetermined intervals in a circumferential direction, and a coil received in the slots. When installed with respect to the magnetizing yoke, the magnet section is arranged to face, at locations closer to a d-axis, magnetization surfaces of the core and face, at locations closer to a q-axis, the slots of the core. The magnetization surfaces of the core are formed between the slots adjacent to one another in the circumferential direction. The coil is fixed by a nonmagnetic and elastic fixing material in the slots. On a facing surface of the magnet section which faces the magnetizing yoke, there are radially-recessed grooves formed respectively in q-axis-side portions of the magnet section.
